This is more involved than simply "install a Heli-coil".
*This is a large threaded part and it is metric fine thread which adds to the problems of sourcing inserts.
*The hole will need to be bored (not drilled, due to size) to the proper diameter for the insert tap. And, the bored and tapped hole must be aligned properly and sized properly to a few thousands of an inch or 0.0xmm for the repair to even function.
*Then an insert installation tool must be used to install the insert.
*The insert must be flush or slightly below the sealing surface of the hole or the insert above the sealing surface will cause a leak.
*None of this is going to happen using a "hand drill & tap wrench". To do this properly, the pan will need to be set up on a mill... if you go this far, many as well bore it out and thread the hole to the next size up and use a different threaded plug, metric or inch size makes no difference here, it's what will fit best that matters.
*This "ain't" wood working where it the parts don't fit, ya "pound it till it fits.
*Re-threading the stripped out hole to a tapered pipe thread is possible, but I really don't like tapered threads as they stress the wee out of the parts and can cause cracks and other broken bits if over torqued.
Your best options is to get another pan and be careful of who changes oil on the future or remove the pan and take it to your friendly local
machine shop and have then bore, tap the hole to the next size up.
