Exactly.
If there are 15 war gods, why would one decide to be a racial diety. One can think deities don't think like humanoids but it doesn;t take more that a few brain cells to go convert more than one race.
Why wouldn't Gruumsh want to convert dwarves? He'd want to convert them or actively attempt to absorb their war god.
So Gruumsh would attempt to broaden him to snatch up people of all races. With Punk Rock and Sports!!
Does Gruumsh get to make the choice? Gruumsh might command his priest to attempt to convert Dwarfs but in the end it is the Dwarfs who must give the beleif and in beleiving the diety becomes Dwarfish and changes to fit the Dwarven view of their gods.
