I am looking for a type of clutch similar to a sprag clutch, but one
that allows the inner ring to rotate freely, in EITHER direction,
but engages when the outer ring is moved. Does this kind of clutch
exist? And if so, what is it called?

The centrifugal clutch in a chainsaw, snowmobile, go-kart etc might
give you some ideas.

I had to go out back and look. The reel drive clutch on my 1950's
lawnmower engages outward like a centrifugal clutch when the conical
end of a sliding shift sleeve pushes out a clutch shoe actuating
lever.
