I've shown you the Eglot traces for one test case on both Debian pylsp
(failed) and Fedora pylsp (succeeded). I still have no idea whether the
Debian flavour is inside the LSP specs or not. But if it returns
out-of-spec replies, I guess eglot should raise an Emacs error
indicating this fact.

Based on this fact, you could always catch this specific error in the
tests, and say that the server is not suited. Whether you shall skip or
err out the test then is something else; until now it isn't obvious that
a failed eglot test is due to the (possible) server misbehavior, or due
to an eglot error. At least this information should be shown.
