That's because when they moved from two letter to three letter airport codes, some airports just added an X where there wasn't a logical third letter.

If Los Angeles' 2 letter code had been LO, the new code might have been LOS, but since it was LA they chose to add an X. Same thing happened to Portland, which was using first and last letter (PD to PDX) and to Phoenix (PH to PHX). For Phoenix it actually works out okay because of the name.
