Well, the Pokeball is sort of a representation of Pokemon as a whole, something used to contain Pokemon so you can use them in battle - since Pokemon don't actually exist in this canon, it makes sense for the Pokeball to have the ability to use basically every Move ever. Attracting animals is still a valid ability, sure, but sometimes that happens with artifacts, having multiple valid properties (it's partyl what's kept me from making artifacts myself lately). If anything, that property could go to some other Pokemon-related artifact, perhaps one owned by its creator or something?

Convention Aisle artifacts tend to have abilities directly taken from their source material, rather than some equivalent ability like you suggested. That's more to do with what fandom artifacts are than the creativity of their maker.
