It auto dodges when they never connect, but I'm not sure about afk. If you don't pick a champ it gives you a random champion. there's no real way for the system to distinguish the difference between an afk and someone who simply didn't pick.
I would also like to see the player get booted and everyone else requeue if they don't pick a champion. Giving someone a random with no time to adjust runes, masteries, or summoner spells is just silly.
