Not really. Truly no printed plastic is food safe due to the pores created during the printing process. These pores can house hard to clean bacteria.
There are coatings you can use to eliminate pores that are food safe. But I’m not familiar with them so I couldn’t really point you in the right direction sorry.
It is possible to smooth PLA using ethyl acetate, but I don't know if that's good enough for food safety, plus you have to remove the ethyl acetate itself.
PLA won't survive in a dishwasher. PETG might, but there are no reasonable solvents for smoothing PETG.
Maybe it'd be best to print a mold in PLA, smooth with ethyl acetate, clean thoroughly, and then pour silicone into the mold.
