Eh, no.
It's not the same as me "reading a bunch of books and writing another book using your accumulated knowledge", it's the same as me stealing a bunch of books that I then read and write another book using my accumulated knowledge.
Glossing over whether "building a statistical model of a language that allows for probabilistic generation of plausible text" is any way similar to "accumulating knoweldge" the crime alleged is the initial theft, not the subsequent "writing".
