I don't really know much about live oaks...but the most active feeder root
system for white oaks coincides with the dripline.  That's where we're
supposed to fertilize them ... and that's where the most intense competition
for resources would be.  That area would receive the most sun to dry out
plants, and it might make enough of a difference during droughts to cause
trouble for your grass...resulting in a dead ring around the live oak tree.
