L3 and R3 were part of the original PS1 controllers, havent you ever used a Dual Shock? 
anyway, the only game that comes to mind right away is Ape Escape. i know there are a few more.
but if you cant think of any games, what is the harm of binding them to the stick buttons? not like you'll ever use em
