My understanding - which could be incorrect - is that the original
motivation/justification for "Assisted-by:" tags in the context where I
understand them to have been first been used, that being the Linux
kernel, was not about "in case the content is ruled not copyrighted",
but "in case the content is ruled to be copyrighted by virtue of the LLM
that produced it having been trained on copyrighted material". That is,
the idea was "if courts rule that the output of LLMs trained on
copyrighted material is subject to the copyrights and licenses of that
original material, we'll have a legally-enforceable obligation to be
able to identify which things in our source trees are derived from the
output of those LLMs, and remove that tainted content".

Whether or not that's a realistic concern (then or now, since IIRC there
may have been some rulings which could have gone that way but didn't?)
is a different matter, but that at least seems like a distinctly
different consideration from "can it be copyrighted at all?".

The above is about a channel of vulnerability to such need for removal
that probably only exists (and almost certainly could only be annotated
in this manner) with LLMs, however.
