Disable Leap Motion App on Startup

You will find a line item

com.leapmotion.Leap-Motion.plist

Library/LaunchAgents

Just rename from .plist to .bak - incase you would like to auto startup again.

I believe Leap Motion chose to use LaunchAgent rather than 'Login Items' is because they couldn't get it to startup all the time.
