Nordstrom Consulting v. M&S Technologies, which is possibly the most relevant case, describes a process for developing under a clean room environment and from what I understand it seems to focus on isolation of engineering teams and resources (except when required for interoperability). I did not find mentions of assessing the cohort of engineers for prior access to the copyrighted material but if I have missed that please let me know.
I also wanted to say that I am not asking this because I am thinking to start an unethical license laundering business, I am only trying to understand the meaning of making LLMs legally equivalent to human workers.
