Azir's soldier auto's attract minion aggro even though it's considered a spell
Azir's soldiers' auto's do not proc on hit effects since they are considered spells but they still attract minion aggro as if they are indeed auto's.
In the past you could argue that azir's range made this more fair but with his decreased range, it could be a small quality of life change to remove aggro since technically he shouldn't attract aggro with spells
