But... reindeer are animals too...
In any event tho, on a character-design level, its because deer antlers are considered to have more of a "nature vibe", and so they're usually used with character designs that are trying to create that association.
There are also other esoteric associations, like the Baphomet being a goat, or the association between The Devil Arcana and Capricorn within the tarot, but I find that a little "wrong-headed" in associations with succubi, since those "goats" are very specifically associated with worldliness.
Ultimately it does just come down to "human ideas of character design"...
