No. LARL is simply the relative addressing version of LA (LOAD ADDRESS).
I suspect you are getting confused with LAE (LOAD ADDRESS EXTENDED), which loads the requested address into the specified general register, and also loads a value into the corresponding access register.

This likely sounds really stupid, but when I am in AR mode, and I do an LARL, does that instruction set the corresponding AR register as well as the specified GPR? I looked at the LARL instruction in the -9 PoPS manual. It doesn't say, but refers to other instruction such as Branch And Save Relative Long. But none of those mention the associated AR either.
