Excellent and hilarious premise for a cyberpunk mission. I like that it's also about the PCs working to repair something crucial--like actual utilities workers--and doesn't involve them shooting people. It's a nice breath of fresh air. I think some players might chafe at the lack of combat encounters, but that can be mitigated by good onboarding by the GM. It also all ties really well to the themes you decided to use.
The NPC breakdown of the different AIs and their relationships to each other are all really excellent. I do think you could provide some suggestions to the GM on how to hint at or reveal that the AIs are in a polycule. Just a couple more clues beyond the optimizations. But that's pretty minor and would be easy to add in.
