I do not know if it counts but the SWKotor games had a lot of alien languages and they´re dubbed, (Twilek, jawa, bodan, droid, etc) but your avatar seem to know a lot of them and/or you have a translator droid (best diplomatic translator droid ever HK-42)
It seemed to me more like saving money on VO - Full VO without having to record full VO. You reuse same lines and subtitle different stuff. Quite a bit like Supergiant's delightful
Pyre are "voiced".
Experimenting with "languages" in an RPG could be interesting thing to play with - though I won't hold it against Larian for not tackling it. I don't think this is the most cost-effective reactivity one could spend money and time on.
