Not really?

The torture stuff may have been fabricated by the Marquis to justify the killing of minors, but the rest is very easily traceable. We know she visited Berlin during the Olympics. We know she was buddy buddy with the Gestapo. We know she fed them intel.

We know during Vichy she was given preferential treatment by the Nazis/Gestapo.

She was a Nazi agent and collaborator, and was very pro Reich. She just may not have been a sadist. Which is splitting hairs, as she'd have known what they were doing to minority communities. She was openly supportive of people who were rounding up and killing people.

Yes it's not fair that they took away her ability to compete, but that's no excuse for knowingly participating in a genocide. She deserved her death.
