4.1.1 is a very naive SC that fails particular "code smells" because
they *may* cause problems in different user agents, which then *may*
have an accessibility impact.

See discussion here about deprecating that SC altogether

I would say: if the 3rd party solution could be nudged towards not
spitting out invalid HTML, that'd be good. Otherwise, just take this as
a mild failure (as it incontrovertibly is a failure of 4.1.1), but
document that you're aware of the failure and don't find it has any
actual real impact on the accessibility of the site/page.
