WHeather the cause was toba or something else does not change the fact that the bottleneck effect on homo sapien was there. whether the bottleneck event directly or indirectly caused the migration out of Africa also does not change the fact the genetic evidence not only supports OOA by a small group, it maps out the route routes the major present population took once the single small group left Africa and split up into different groups.
So the fate of neither toba theory nor the bottleneck effect can challenge the OOA hypothesis of non-african homosapien origin.
