Training stores a variation of the source material, which is arguably distribution. And selling the result or selling access to it certainly is. So fair use applies, and hoping a court thinks the process is transformative to count as fair use. Given original material can be spat out, my money is on a court thinking this is about as transformative as a compression algorithm.

Selling the result is where it's on dodgy ground. I disagree about storage though.
