The page 'Malls and Shopping Centers - LAX Area' has various place close to LAX, the same site also has lists for other areas of LA.
I haven't been to any of the ones around LAX, I guess they are pretty generic but maybe good enough for your needs. If you want to escape the malls, Third Street Promenade in Santa Monica is a nice enough pedestrian area, but it's a bit further away, but the beach is really close.
