> An LLM trained on the Internet-at-large is also presumably suitable for a clean room design if it can be shown that its training completed prior to the existence of the work being duplicated, and thus could not have been contaminated.

This is assuming that you are only concerned with a particular work when you need to be sure that you are not copying any work that might be copyrighted without making sure to have a valid license that you are abiding by.

The "clean room" in "clean room reverse engineering" refers to a particular set of trade secrets, yes. You could have a clean room and still infringe if an employee in the room copied any work they had ever seen.

The clean room has to do with licenses and trade secrets, not copyright.
