If the DM recognizes that True Strike *only* has a subtle non-verbal component, then it can be good just before a battle begins, like when you are about to ambush ...
If not, the cantrip is an utter waste of cantrip. It is a long-time complaint from 5e players.
So, for BG3, if it can be used without triggering combat or automatically give that character the "surprise round", it can be good.
Nb : I think they made it 60 feet in BG3 to help a bit.
