I can say with certainty that more types of cc interrupt her ult than just stuns. Polymorph, silence, knockback, knockup, knock aside, pull, airborne, flee/fear, charm, taunt, suspension, and suppress all interrupt her ult.

In addition, moving, casting abilities, casting ignite outside range (and most summoners), and using most (if not all) items stops the ult.

In fact, you would be hard pressed nowadays to find champs that cannot interrupt her ult. All champs could always just kill her, and now all champs can also stun her thanks to braum. Most champs also have at least one of the ccs listed above, (I think the record is three, held by blitzcrank.) There is certainly no need for riot to create more types of cc to stop kat's ult. True, some existing ccs are not easy to land on her (sej q, mao q, some ccs that require an aa) but many are exceedingly easy to hit, especially since she is stationary (targeted cc like fiddle, targeted ccing abilities like annie, area cc like leona r, ranged aa stuns like tf)
