Opening most of the seals took in the span of those decades, over 50 of them. Finding the right individual to open the last seal took decades of planning. Death was binded by Lucifer, that was the only reason why he bothered to give the ring to Dean. Other than that he doesn't care about earth or the apocalypse which he already admitted. The length of time and proven feats shown does make up for strength. Meg is not a boss. She is more a mid-boss along the lines of Crowley. Don't know why you bring her up. And finally, God never destroys his creations if they are doomed failures or betray him. He locks them up. Like he did with Lucifer. Chances are it was probably Michael ordered by God to lock away the Leviathans into Purgatory. God doesn't step in personally, he lets his top angels do his work.
