It's gonna be copyright infringement.

You can even cut a few scenes and make up a few scenes entirely, too. You're still getting busted.

creatively transform and apply for some tasks maybe not violation

We as a society have determined that certain sorts of non-consensual copying are allowed: "fair use" broadly, and maybe you can consider "mental copying" in this category. Maybe we'll add LLM training to the list? It's not like copyright rules are a law of nature: we created them to try to produce the society that we want, and this is an ongoing process.

Again, I think there are fascinating questions 1) does LLM training violate existing copyright law + case law or does it maybe fall under a fair use exemption, and 2) is that what we want. But I think "do LLMs make copies" is dull and trivial and I don't know why it comes up.
