Reverse Missiles / not an "attack"

If what the spell does is reverse the projectile's velocity state, that could be an issue. But that's not what the spell does - it specifically sends the projectile back at the shooter, which may well require it to arc the shot or similar.

As to "hostile intent" (which I don't think is part of Reverse Missiles, but apparently is part of some spells), that doesn't necessarily require any sort of mind reading. In many settings - particularly various flavors of shounen anime - "hostile intent" is a detectable force/energy that is produced/released by anyone acting as such. It may be possible for someone to engage in hostile action without any hostile intent, but this is likely to be the exception rather than the rule (there's an antagonist in Rurouni Kenshin who has sufficient psychological damage as to not generate such). How to handle that - and if it's even an option - would ultimately be up to the GM.
