There are 100 brands. Just search for "food grade silicone grease" on amazon. It is really common. It is used for everything from o-rings on scuba equipment to meat grinders. Amazon has two dozen brands and it's all the same stuff. It is FDA approved for use near food so it will not kill you if you eat it or get it on your fingers. I just used some from my diving supply kit on a water filter I use for backpacking, the brands interchange. Any of them work for any purpose.
I think the suggestion was good because this stuff does not attack rubber in o-rings and has no nasty solvents so it will likely work on PLA. You only need a film so thin it is nearly invisible so the cost is not much. My tiny can of "Neptune" brand grease has lasted 10+ years as I only use it to lube small size o-rings after cleaning with Simple Green.
