Because Griff is 4th Commander of Demon Slayer and by lore wise he would get one, confirmed by the producer that he would likely get OE even without the list, and he's on the 30 Top Units to be OE candidate. You should be more curious why the hell Iris got one in the first place.... Because she wasn't even in the 30 Top you know... Iris got supported by the fact her lore is heavily connected with Griff and Mora.....
