I suspect that if you don't change the /sector/ of computing you are working in, you may run into the same thing elsewhere.
AI is being adopted mainly where it works, and where it works is where regurgitated code cobbed-together from what has been seen before is sufficient to get the job done.
Assume that your CEO and CTO are not complete idiots; that they have some rational argument for believing that the approach will work. It's also possible they are gambling on an experiment; if it fails, they will back off on it.
If you want to avoid being told to use AI, you have to work on legacy tech stacks that AI doesn't understand; algorithmically complex code; critical infrastructure code where one bad bit stops multiple machines and applications; safety-critical embedded where AI slop could maim and kill and so is out of the question, etc.
