I have not seen organized religions around AI yet. But I have seen people writing some pretty wild ravings about how their god is an AI and how chatgpt connects too it or something. There's also people dating LLMs. Some guy in Belgium commit suicide because his ai gf told him too leaving his wife and kids behind
It'll be interesting to see how these sorts of less than anticipated sociological things emerge. Take a look at scientology, many practicers, pretty scifi beliefset, I think all we really need is another L Ron Hubbard and lots of not super crazy people could start to worship these things.
