When I read FAR Part 103 it says that ultralights must have a power
off stalling speed of no more than 24 knots.

When I go to the Windward Performance web page it shows the stall
speed of the SparrowHawk as 32 knots.

How can the SparrowHawk be flown as an ultralight in the U.S.?

Because the stall speed requirement only applies to POWERED
ultralights. No motor = no stall speed requirement. Read the reg
carefully. I think you will find there is only one requirement for
ultralight gliders.
