If LLM assisted reverse engineering is deemed illegal by the courts, is that precedent for a class action that asserts OSS licenses are violated by labs that trained LLMs on that code?

There are two modalities for this;

1) LLM being post-trained against a decompiled binary - then used to output working source code.

2) LLM being used to analyze decompiled binary and used to output working source code.

How can it be "clean room" when an LLM is trained on or reads OSS but not clean room when the same is done for decompiled software?
