That's the right folder...
But I can't say if that would work or not, I don't know anything about "Winlator", nor have I ever tried playing on a phone (card carrying member of the Glorious PC Gamer Master Race here).
The BepinEx translation plugin is a .Net assembly, so I would guess it would need a full .Net runtime for it to work correctly.
Can't help beyond that, soz.
