Yeah, I think it's basically for the same reason that Gandalf doesn't call upon the powers of an angry God and smite the shit out of evil. For one, it would be a boring story for another the Valar don't work that way. They picked up and went across the sea because they thought shit like that was pretty dumb.It's been years but I seem to recall them as if they could only be summoned in the most direst of situations. Sort of like how Gandalf can't use his wizarding powers unless its truly called for.
I'm fairly sure that the Eagles (or at least the eagle king) is the same sort of thing that Saruman / Gandalf / Radaghast were. Basically Angels... but the white council was sent back to middle earth as a sort of counter to Sauron where the Eagles were there since the birth of the elves and never left in the first place.
