The two champions with ammo don't have standard AAs. While Jhin's is for the most part, the scaling on it is entirely different. Giving them ammo would make attack speed function really funky, the entire attack speed system would have to be overhauled. And what about for someone like Kog'Maw who just spits at you or Ezreal who fires magical bursts of energy? I know thematics don't always correlate to gameplay but it'd be a huge disconnect if suddenly Kog had to "reload" his spit.
I had actually been pondering what an ammo system on Kog would look like.
Make him a melee champion with a bite attack. Whenever he last-hits a minion or monster or gets a takedown on a champ he eats them and gets some number of stacks of ammo. His W becomes a targeted spell that consumes a stack of ammo and lobs an acid blob as per Live. Then Koggy gets a new Ult that fully fills his ammo meter and replaces his basic attacks with the W slime wad for the duration.
