There's a few options you can use. One is the Technique is shooting an electric blue pentagram towards the direction of a psychic attack, dispelling the negativity and then doing the LBRP. You could also do a mirror spell but that has a problem of you not being aware that it's a true psychic attack and therefore reflecting that against yourself.
Also, you could make an Earth Pentacle like the Golden Dawn uses. It would be a giant shield that you can use to store negative energy and use it for other purposes, like charging a talisman or amulet for the same reason!
There's also swords you can use in case of a serious fight with a demon that, much to the chagrin of others here, you can use those too. You'll need one for them in case you get into that level. Best of luck!
