Okay, let me be more specific...A MELEE and NONTANK champion:
That should narrow it down to:
Now let me discuss why they don't need one.
Pantheon: Indeed, he is difficult to get away with. I main'd for a while with him, so I definitely know. While his stun does bring you to them, it usually last long enough to make an effective escape, and (a bit overdone) if in a real desperate situation, you can use his Ult to escape. (Not much of an argument here, I'll give you that).
He can break all CCs. His main DPS is a range.
His Ult is a snare(admitedly, not a game breaker).
Shooting a creep, his movementspeed is increased moderately.
Might be getting somewhat closer. He is a melee class, but his skills grant him moderate ammounts of lifesteal and movement increasements if near half-health champions.
My point here is, Akali is a melee DPS that doesn't have any survivability other than hoping you can kill them before they kill you. She has no way of stunning champions, or of breaking them. She has no way of outrunning, or out tanking.
