I used Molykote Z in the LOX valves of my rocket without incident. I
used gloves and rubbed it on the ball and seats, then wiped off the
excess. I don't know if it reduced actuation forces though.

Molybdenum disulfide, superficially similar, *does* work as a lubricant in vacuum, and hmm, it seems to be considered LOX-compatible too (says here to look for "Molykote type Z" or some types of "Oxylube" -- caution, my source on this is old).
Ah yes, <https://www.tsmoly.com/molybdenum-disulfide-powder-moly-powder-technical-fine-grade-p-195.html> specifically cites "liquid oxygen valves" as a lubricant application for molybdenum disulfide powder.
