Is there a reliable way to have Vout low when Vin is low? Circuit can represent any optoisolator such as a TLP785.

If by 'gate' you are referring to a simple logic gate then yes, but if you are referring to the gate of a power FET being switched rapidly then no, since most opto-isolators wouldn't handle sufficient current.
