No.
I almost never see lamb chops in American restaurants. Rack of lamb yes, in expensive restaurants, and sometimes steak restaurants.
Lamb ribs in a famous rib place in Memphis.
Lamb at Mediterranean restaurants, usually gyro/shawarma meat.
American restaurants don’t even put it in shepherds pie, and it’s supposed to be lamb. Beef is technically cottage pie.
I buy lamb chops once in a while in the supermarket. Lamb is quite expensive.
