Observing the bending of light is only one test of relativity. Detecting a gravity wave is another; and it's a different phenomenon. Any interference seen in the LIGO apparatus will be due to the warping of space-time as a wave passes through - space-time fluctuates. The bending of light is an observation of a static effect, of how gravity shapes space-time.
