Can't you just unbind Magic Missle from your left-click and have it set at whatever they call "auto attack"? That way you'd have just run up to the enemy to try to melee (and out of green stuff), and it would still allow you to interact with vendors. There's probably something I'm not considering here, but I'm not quite sure how you have MM keybound (both to LMB and a keyboard key?).
