Did you try contacting the winery and asking if they have a US distributor you can contact? Or the winery can probably ship direct to you. I’ve bought wine in Europe at vineyards that ship. It’s expensive ($10-12/bottle) but doable
I would try just buying yourself a bottle and sending it via DHL they will be annoyed about shipping it but I sent myself wine from Cyprus that way. Just beware the French national slogan should be c'est pas possible so even DHL because it's France might say no but I'd try it for €12 euro
That wine was sold in numbered bottles I had to pay a source to get when I lived in France and it turns up on the shelf in a wine store off market st next to cvs.

I found a super hard to get wine I’d loved in France - in a tiny wine shop in SF.
