I’ll leave this as a memorandum.
It seems that you can avoid crawling by AI bots by putting the following in robots.txt. That said, there are apparently some AI bots that ignore robots.txt, so I can’t say for sure. If you really don’t want the AI to patrol your site, the only option is to use the Simple Membership plugin or something to put your content behind a login wall.
