Yes, you can call them direct, but LA, like all the other airlines in your itinerary for which you hold open sectors, will want to know your ticket number.
...Is SCL-IPC and back tough to get on as well?...
It's February, you are competing with a lot all the people wishing to see the moais on a sunny day... yes, it's tough, although not nearly as tough as SYD-AKL-SCL.
