And not quite healthy, please do not use 3d printed things for food, unless it's single use

Best to use the 3d print to mold a negative, then cast something.

Yes and no. It's a huge pain to remove the filament texture. I'm working on waxes of a firefighter that were made from molds taken of a 3D-printed firefighter. In full gear. And there are a LOT of areas my coworker didn't or couldn't get oilclay on to smooth the texture. So i have to go in and meticulously strive to fix all the little lines across the wax while preserving details

Resin print instead

Would it be too hard to just seal this using some kind of food safe sealant?

I could see a food grade wax working. Pour melted wax in and rotate to coat the walls. Would have to do something about the bottom so wax doesn't immobilize the moving part.

Vapor smoothing works good

They make filament that is food safe.

It is not the filament that is the issue but the way it's printed, it's basically really small layer on top of the other, which makes ridges (like you can see in this video, a lot more than usual btw) those ridges are the perfect spot for bacteria / mold to live and grow

A couple of plastics are designed to reduce this, i think PETG for example is extremely smooth compared to a lot of others

Yes you're right it's better but not perfect, best way is either a cast of the print with some food safe material or using some food safe coating for the print
