It's my understanding that previous generation LEAFs cannot feed power from the J1772, but the current generation can.
I don't know what it would take to modify an earlier LEAF to feed power from the J1772, but every example I've seen uses an inverter connected to the 12v system, as you described.
I've not heard of any official support be it in a vehicle or via the SAE standard for J1772 for a car to output power from its inlet. It's for charging only. Years ago at CES, it might've been at the Yazaki building outside CES, they had a proposal to get power from an EV via J1772. I might've taken a picture but I did ask about the standard not supporting it. I think the answer was that it was just a concept.
CHAdeMO support V2H and V2G but the vehicle needs to support it, as well. JDM Leafs have had support for it probably since the beginning. See below.

Unsure which years or revisions of US market Leafs can do it. I've personally seen Nissan-supplied gen 2 Leafs (supposedly) powering a V2H box via CHAdeMO at EVents (e.g. Cupertino EVent years ago before '18 Leafs were shipping in the US) and at Nissan's booth at CES in Vegas. Unclear if the cars were modified/special.
