It's there you just have to look for it and drop the attitude of "Larian doesn't care" and I'm sure you'll see it. Fun fact - Larian made all of their developers play the original Baldur's Gate games before starting to work on the next title. Just a fun small example
Why do I have to look for it then? Why can't they be more blunt about it like "yeah, we all love PnP D&D, we love the BG games, we want to make the best D&D game ever" instead of saying that they're inspired by FF and the 5e system does not work in a video game?
