NO, but it did have ocean over it, as recently as the Miocene (Pico and Monterrey Fms are evidence of this). But bottom of the ocean can't happen on continental (or even transitional) crust. It was a shallow inland sea (kinda like Hudson Bay).

Obviously the metropolitan area wasn't but the area now occupied by LA was. There are numerous formations which reveal how the coast line migrated back and forth (up and down). As the water levels rise, the shoreline moves higher in elevation. It generally leaves behind a coarse grained layer. As the coast migrates inward, those coarse grained layers get covered by finer grained off-shore deposits. There is also much earthquake activity and the land has been raised in some places. I personally have drilled in places in LA and found sea shells.

Hi. It has been under water before and may soon be again. Climate change.
