Los Angeles - LAX International Arrivals

Last year I flew AZ from FCO to LAX and was surprised that we arrived and cleared immigration and customs in terminal 2. I was curious as to which international flights arrived at which terminal and went to the LAX website to look this up but could not find any info.

Could someone direct me to a site where I can find out where the different international flights arrive? Thanks.
