There is no agency bot lane. ADC's are just the best end game champion class, but they have little to no control over how their laning phase goes.
The game is decided by your jungler and your mid laner. It largely doesn't matter how bad or good you do bot. Whoever gets that 4 man gank bot lane starts the snowball.
Games are formulaic in this way. Junglers invest everything into mid lane. The better mid laner roams bot. The 4 man ganks either breaks the enemy bot lane or puts them on life support. The group takes the tower, then the dragon. Top lane throws a diva fit because they got no ganks. There's little variation.
There's an added complication of bot lane requiring coordination as well. If one of you is off, then that makes everything a thousand times worse.
