How complex does a mechanical transformation have to be to not be considered plagiarism, copyright infringement or parasitism?
If somebody writes a GPL-licensed program, is it enough to change all variable and function names to get rid of those pesky users' rights? Do you have to change the order of functions? Do you have to convert it to a different language? Surely nobody would claim c2rust is transformative even though the resulting code can be wildly different if you apply enough mechanical transformations.
All LLMs do is make the mechanical transformations 1) probabilistic 2) opaque 3) all at once 4) using multiple projects as a source.
Legally speaking, this depends from domain to domain. But consider for example extracting facts from several biology textbooks, and then delivering those facts to the user in the characteristic ChatGPT tone that is distinguishable from the style of each source textbook. You can then be quite assured that courts will not find that you have infringed on copyright.
