I don’t think so. Lotr is pretty sound and even the eagles my doom thing was explained by Tolkien.
Part of the neatness of the world to me is how everything fits together. Dwarves don’t decide to randomly shave their beards. Elven kings don’t scheme against their subjects. Nothing happens randomly in lotr or even the hobbit book.
If you nitpick like that, you can find a zillion such questions from the Lotr trilogy, the books themselves.
