I think the Aura Sphere is supposed to be a Attack based dragonballs projectiles created from the users inner Ki aura. It's not that surprising for a pokemon heavily based on physical combat.Riolu naturally being able to learn Aura Sphere as a level up move in Pokémon Legends Arceus is a nice callback to the second Pokémon Ranger game and brings things full circle.
