This is a fine line to thread and I haven't seen the movie so I can't comment as to how the handled it, but while the Freemen don't have interplanetary domination in mind and Paul does lead them to Jihad, it's not like Avatar where the native are being exterminated and some random guy leads them to military success.
The ridiculous thing about that narrative is that an alien with their own agenda (most likely not for the benefits of the native) is somehow given leadership
The thing is all of that is explained in much more detail in the second part of the book. You know, the part that's not a film yet.
it seems more like condemnation of the concept of leading, or controlling, as opposed to educating and liberating. The white savior element is not neccessary to convey that message.
