If you loan a pencil to someone and they stab someone to death with it you could get sued.
If you loan a lawn mower to someone and they cut of someones foot with it you could get sued.
If you loan a cup of sugar to one neighbor , and he pours it in another neighbors gas tank, you could get sued.
Hmm, not sure if you understand how the law works. Sure I could sue you for just about anything, not that I would win, but loaning a pencil to someone who then uses it to kill someone is not a punishable offense.
