"We can't have BKB in league, because bruisers are supposed to be kited"

Follow this logic

"we can't have Zhonya in league, because mages are supposed to die if they get caught out of position instead of abusing their range"

"we can't have GA, PD, DD, Lifesteal or BT shield because ADC are supposed to be easily killed which is their weakness"

FYI, BKB doesn't: stun the enemy destroy created terrain isn't permanent, and can last for 2 or 3 or 4 sec like gargoyle stoneplate

last time i checked, Olaf can still be kited even with his ult.

Face the truth: CDR stacking made cc extremely cancerous, we don't have anything to deal with it as bruisers, QSS doesn't work because it gives adc stats, and bruisers are facing 5 or 8 ccs unlike other champions

just make an item giving cc immunity for 2 or 3 sec and give it 300 hp and 20 ad stats

or something like that
