They aren't republishing or reselling. In fact, they buy huge amounts of books and then destroy them, which is better for the rights holders than to resell them.

That's terrifying waste of real world resouces for no other purpose than satisfying the letter i of the absurd rent-seeking-enabling laws.
Not reselling? What am I paying them for then?
Since whole chunks of these books can be recited verbatim by these models, to which they sell access, they absolutely are republishing and reselling these books' content in a way.
Like I remember a research paper that managed to recreate the whole of a Harry Potter book from a model?
