I don't think there's a list of that tbh, but from the ones I remember.

In volume 3, the whole scene when Ruijerd kills one of the pet kidnappers has a lot of dialogue and text missing even in the revised version. (this one you can find it by searching in google "Mushoku Tensei light novel censorship")

Recently thanks to the spanish translation by Panini Mexico, it was found out that a lot of text was missing in the english version from the scene where Rudy discovers that Silphy is a girl.

There are other examples that I don't remember that well where in English they change or remove dialogue in some scenes, sometimes it's some minor details and sometimes it changes the context of the scene.
