That really isn't the issue, and no, that would not be permitted here. It would be one thing to note that an LLM was used in some part of the project, it would be entirely different to criticize the poster based purely off whether or not there were any contributions involving LLM.

That would be a rule 1 violation.

If you want to comment on a known vulnerability, thats one thing. Commenting that its vulnerable because an LLM had a pair level patch is not.
