No one literate pronounces it Los AngeleEEs. I lived there for four years in the 80’s and no one pronounced it like that unless they were trying to be humorous in a low IQ way.
Unless, as others have pointed out, you’re Arlo Guthrie and you need it to rhyme with “ki’s” as in kilos.
I’m old and grew up there. Yes, Mayor Sam Yorty pronounced it AngeleEEs. He was born in the midwest (Iowa IIRC) but not sure how old he was when he moved to LA. He and LAPD Chief Parker cleaned up the corruption of the Mayor Poulson era. I mark the beginning of LA’s decline with Yorty’s loss of the mayoralty to Tom Bradley.
