Yeah, that is my take as well, at first I thought it was completely useless just like the old Facebook posts with users posting a legaliese sounding text on their profile trying to reclaim rights that they signed away when joining facebook, but here it is possible that they are running their own instance so there is no unified EULA, which gives the license thing a bit more credibillity.
But as you say, bots will just ignore the links, and no single person would stand a chance against big AI with their legal teams, and even if they won the AI would still have been trained on their data, and they would get a pittance at most.
