This is not correct and a common misunderstanding of the court ruling. The verbatim output of an LLM is not copyrightable. If you create a work using an LLM, this IS of course copyrightable.
When "using an LLM", means the human has to substantially alter the output of the LLM for the work to be eligible for copyright. Agreed.
But this makes the LLM tool different to other tools. If I author a novel using a word processor I don't then in addition have to substantially alter that output in order for the work to qualify for copyright.

It's like, how substantive would changes to J.K. Rowling's Harry Potter need to to be in order for a derivative work to qualify for copyright? Now apply that to the output of an LLM.
