Offline AI limitations

It's not about AI in real life. It's about AI in a Sci-Fi setting.

So I've been playing around an idea of a Sci-Fi story that is taking place on a stranded O'Neil cylinder. Long story short a defensive AI went rogue, killed a big chunk of population and made 80% of the O'Neill cylinder basically uninhabitable. And then another AI basically started creating cyber-zombies pretty much at the same time. So they had two major AI rebellions happening the simultaneously. But also I want to have some androids in the story. So going the whole Dune/WH40k route of "no AI aloud" isn't really something that I want to do.

Currently my "brilliant" solution to this issue is that is basically prohibited by law to house any kind of AI in a storage medium/mobile platform that is capable of connection to the network. What I mean is - those androids can exist but they do not have any ports to connect to other devices by any means. Like they do not have a network adapter any any kind of ports are removed after programming the core.

So I have two questions about this idea.

1) How stupid this idea sounds?

2) Do you have any other ideas or suggestions about what else can I do about this?
