Do you agree that one can train a human brain or a digital brain on as much copyrighted artist work as one wants? style is not copyrightable, so is training on copyrighted content.

the law (an common sense) implies that as long as you're not reproducing art, you can do this. and latent space doesn't save or reproduce that content at all. It mimics, combines remixes or reinvents it. The same what a human brain is doing after learning how to draw.

humanity wouldn't be where it is now when it's forbidden to learn from inventions.
