I i try to keep to things that won't spoil the plot. So is there some kind of rule about fighting robots? If the Astori feed on life wouldn't fighting robot negate that? But it also seems like there are rules around intelligent AI. Seems like some are considered people and some aren't. Like the companions can't be considered people because they get no choice who they serve, which is why if figure Greye couldn't be left in the custody of his mom because she likely couldn't work or be made the guardian of a living person. To that end are artificial allowed to work? could a company just build a workforce of artificial people, I could see there being laws about that. It was said th4e Sheol had drone fighters, but are those AI piloted? or people with joysticks?
So spoiler I want, is Greye going to get some clothes? I knows he's going down to the planet next book but is he really negotiating all that in his bloody T-shirt and jeans, or a vac-suit? As I theorize what's going to happen next I keep finding myself plotting different way Greye could find his way to an Admiral's uniform, and the rest of the crew. You don't have to tell me what the fix is but is the fix coming?
The robot issue is complex, but in general terms, an all robot army just has too many vulnerabilities from an electronic warfare standpoint. They're terrifying combatants, but there are ways to either shut them off wholesale, or worse still, turn them back on their operators. (Also, there is a very, very good reason you wouldn't send anything robotic against the Ashtor, but that's not going to come up for at least 3 books). Drones are a bit of a different story as they're simple, cheap, can travel in shielded containers before being launched, and can be utilized in more surgical ways that the enemy may not be ready to deal with.
Even so, you saw what happened to the special forces team that the Alliant sent onto the ship at Zephyr. Fiona took out their tech advantage before they even made contact and in a few cases, used their own technology to murder them. Once they lost the advantage of surprise, their power armor became a serious liability to someone with her technical talents. They'd have a similar problem with someone like Greye, once he has fully shed his soft, civilian mindset.
In space, drones can be spread out wide enough that something like an EMP would affect very few of them and there is nothing to obstruct a directed-laser guidance system, so they could not be easily jammed. There is the problem of speed, though. Chasing something that is nearing relativistic speed makes things like missiles and drones an unlikely weapon. You'd need energy weapons almost exclusively to have any chance of hitting. Fighters, drones, and missiles are more territorial weapon types, for fighting over a planet or space station, for example. Something you want to capture rather than just launch a meteor at from trillions of miles away and obliterate. One of the reason the Ashtor took out the orbital ring on Zephyr so quickly is because they weren't trying to capture it. Blasting it to bits with mass driver fire was fairly easy, seeing as it is stationary, relatively speaking. Atmospheric weaponry is another interesting one. Energy weapons won't breach an atmosphere, they just get diffused away, so you either have to use mass drivers, or a specialized type of plasma weaponry.
All of this also illustrates why nobody could believe that the Sheol still had its mass driver systems. Why would a prison ship need anti-material/planet weapons? It should have been stripped of anything that wasn't primarily for anti-ship defense. You'll get some hints on that one in book 3.

Artificial workforces are 100% a thing, but there are harsh regulations against allowing a full General AI to embody itself, so they remain limited in their capacity. Most working robots are also highly specialized by necessity, and people are not, so for less common general tasks people are still by far the cheaper option for employers. Why try to program something with a trillion different functions when you can just pay some schmuck minimum wage to go do it instead? Several Alliant species are having population crises, but there are plenty more that are quite the opposite, so they have no shortage of labor. Or they didn't before the war, anyway.
Companions are a bit of a hiccup in that equation, because what they have is not exactly general AI, but also not exactly specialized AI. They are a bit of a mysterious proprietary technology and you're going to learn a lot more about them in book 3. But the short answer is that the corporation that makes them only makes them for the role they've assigned, and they don't share their patents. Leadership within companies and governmental organizations that have tried to reverse engineer their tech for other uses have had a well publicized habit of becoming fatally accident prone until those operations are shut down.
And you are correct, they do not have the right to raise children absent their Host.

As for Greye's clothes... well, with the Cutters wiped out and their successful escape from the Alliant fleet at Zephyr, problem number one on the ship is resupply. That being said, there are no male Eisheth, so I guess you'll have to wait and see what he comes up with. :P
