This bee-like creature (larger than a bumble bee) was lurking on my compost bins, where there’s a bumble bee nest. Is this a robber fly?

You are correct that this is a Robber Fly in the family Asilidae. The clublike antennae indicate that it is a Bee-Like Robber Fly in the genus Laphria, which according to BugGuide includes 62 North American species. Our best guess of the species represented on BugGuide is Laphria champlainii. We suspect the compost bin is good hunting for the Bumble Bees as these large Robber Flies tend to prefer stinging insects like wasps as bees as choice prey.
