It is true that Leviathans are powerful but they can be killed by an Archangel packing enough juice as in power. Take Micheal for example he is pretty powerful and when castiel used the souls of the leviathans to kill Raphel it was not one soul it was like hundreds combined with his own power and Micheal is much more powerful than Raphel. Just look into it.
