The league wanted LA to win if anything, because if they get a title they might at least some bandwagon fans. LA was supposed to be a cash cow for the NFL, but as usual LA fans don't care about football in general and didn't turn out for the Rams or Chargers when they moved there.
As it stands they have no fans, and won't get any fans, because nothing short of a Lombardi would get them any interest. It's not like the Titans where just making it to a Super Bowl gets them a decade plus of fan excitement, the South loves football of any kind on a level that LA never ever ever will.
