To setup context I'm trying to import this repo to Azure Devops where our team will work and then I would periodically push updates made to the main repo (https://github.com/LibreOffice/core.git) to my azure devops repo.

Yes - back when we had github setup as a mirror, we had to approach
github admins - we did at first due to the size of the repo and
whether they are OK with hosting it, and then for the import due to
the bad commits in the history (conversion from csv to svn to
mercurial to git....)

see https://lists.freedesktop.org/archives/libreoffice/2012-November/041321.html
and also
https://lists.freedesktop.org/archives/libreoffice/2012-November/041333.html
as for why the history has not been rewritten back then...

I think there are a few more malformed ones, but even knowing all of
them wouldn't change things..

No, that's not possible, it would be a completely different repository
then/all hashes would change.

You need someone with administrative powers on azure to do the initial
import for you/need to contact azure support.
