I might be ignorant, but where’s the relevant case law making copyright apply to AI?

I know that copyright definitely applies if you record things 1:1. I also know we’re on the brink of getting new laws regarding AI. But from what I know there’s still nothing that a lower court can safely rely on. And I’m talking EU, as well as US.

If I’m wrong please tell me, I’m excited to learn about what I missed.
