well, yes, because you can demonstrate clean room separation which is
already legally acknowledged as independent invention.

My argument isn't that LLMs can't do this.  It's that doing it is way
more expensive than simply feeding the code into a LLM and asking for
independent reinvention, which is what the guy did to chardet.  In fact
I contend that reducing something to its API and then reconstructing it
is difficult to scale (and certainly is very costly in LLM tokens)
which is why we shouldn't necessarily fear it will be done to the
kernel.
