Mr. Cress isn't the highest person at The Louvre though. There's a panel of people above him, along with the owner of The Louvre itself. I imagine that the owner would not allow any kind of attack, even if greenlighted by Cress. And I doubt Cress would risk everything regarding his livelihood for HiveMind, just so Vonny could have his way.

I only bring this up, as this part of The Louvre's story has always been unnecessary until now. I'm curious for ideas. Maybe Thierry will get his job back, but if he does, he still wants things to be different regarding his family.
