Absolutely use it. More specifically, use Attack Move Click.
Best way to use this is bind a secondary mouse key. My normal setup is to keep left and right mouse buttons the same but use attack move click on my thumb button.
In practice the best way to actually use attack move is to alternate between that and normal right clicking. For example on Kalista, use your attack move button in between your champion and a minion. This will bring you to your max auto range and then immediately auto attack. Once this is complete, you can use right click to reposition without attacking or simply attack move again to reposition while attacking.
Idk how much sense that makes but the best example I can come up with is that. Right click - attack move - right click - attack move - etc.
