Do you have a copy of such a bounce message? If you're getting them consistently, you can set the forward_unrecognized_bounces_to option in the Bounce Processing group for the list settings.
I really would like to see one of these bounce messages, however from the OP, forward_unrecognized_bounces_to won't do it as the bounce was somehow recognized as a DSN albeit with strange addresses resulting in the Bounce message for a non subscriber log messages.
I'm guessing, but I think maybe some spam was sent to the list-bounces address and it contained something matching one of the heuristic recognizers <https://gitlab.com/warsaw/flufl.bounce/-/tree/master/flufl/bounce/_detectors>.
