Is it possibe to buy fresh sardines in Los Angeles, and if so, where?
I've bought them at Quality Seafood in Redondo, they also have anchovies!

I've seen them at Whole Foods (Arroyo), and also the seafood vendor (J&P West Coast Seafood) at the Saturday Pasadena farmers' market.
Before Santa Monica Seafood moved from the Colorado St. location to Wilshire Bv., they used to have them on (very) rare occasion. Maybe they still do -- call and ask.
It never hurts to try the bait shops and barges that cater to fishermen. They often carry live sardines and anchovies... :)
