There is always going to be a human element if you are going to be transacting with other humans.  It seems as if you are trying to sell Bitcoins though because you are talking about using localbitcoins as an "escrow".  In all reality that would be cool if it was run by some non-partisan AI that would be able to help two parties come to an agreement and help the transaction along... but that time isn't here just yet; and unfortunately localbitcoins is run by humans as well.

Better to find someone who has really good trust ratings that seems to be a decent person and ask them to manage a multisig wallet to help the transaction go smoothly as possible between you and the other person.
