This is a female Dobsonfly, and you are correct that they are quite large as North American insects go. Though Dobsonflies are not aggressive, the female has powerful mandibles and she might deliver a painful pinch, possibly even drawing blood, if she is carelessly handled, but the bite is not venomous and it will produce nothing more than a surface wound. Male Dobsonflies have much more impressive looking mandibles, but they are not adapted to biting and they are no threat at all to humans.
