So, yes, I know that due to layer lines etc, FDM (PLA) printing isn't safe for food, however is there a way of making it safe? Essentially I want to create a draw insert for cutlery, so can I print it, the coat it in something to make it food safe?

It's possible to smoothe PLA by exposing it to ethyl acetate (or get a spool of PVB—prints at about the same settings as PLA and smoothes with isopropyl alcohol). As others have already said though, this is probably not needed for a cutlery storage drawer insert, unless you're in the habit of putting your cutlery away dirty.
