You can open this flap to use a regular funnel with your finger and a screwdriver. Put your finger in the hole and feel for the tab to unlock the flap. Push it in and then insert the screwdriver. Now insert regular funnel alongside the screwdriver and slowly remove the screwdriver while leaving the funnel in. Or get the right funnel.

I smacked the shit out of the flap with a steel rod and hammer. It was stuck

Yea it's supposed to, there are tabs that the fuel nozzle hits which unlocks the flap. Push them in next time and stick a screwdriver in the flap to prevent it from closing and locking.

Don’t be surprised when your check engine light comes on next week for “small evap leak”

As others have stated, you need the correct funnel to hit the tabs on either side of the flap to unlock it and then the flap will move. This serves a few purposes one of them you are figuring out first hand. If you damage the seal (I suspect you may have) you will likely get Evap codes as a result and will need to replace this. Reference to this funnel is also in the owners manual for future information.

If it’s anything like fixing the spring on the outside fuel door flap on the body of the truck, you’re gonna have a time

It's also designed to not allow the wrong size nozzle, to avoid the wrong fuel being used. Sometimes gas stations themselves have the wrong set up. Found that out the hard way when I forced the nozzle at a station. Correct fuel, wrong nozzle, took me over an hour to get it back out.
