Make AI 'pay' by delaying every request and presenting the content with a warning on top, like: AI bots are (sc)raping the internet, that's why we do this.

Or something like: AI is making your experience worse, complain here (link to OpenAI).

Maybe not the most technical solution, but this at least gets the signal across to regular human beings who want to browse a site. Puts all this AI bs in a bad spotlight.
