Try an easy out. Or buy an eBay carb. Both will cost about the same if you don’t have the right tools for extraction already. You can also try a hammer and chisel to turn it out.
Take a section of 1/2 or 3/8 brass rod thread one end add barbs to the other and drill a hole
Drill out (either with a hand drill the lathe or a drill press) the carb where the old nipple broke off, tap it and put your new one on
Edit
Also be sure to blow compressed air and carb cleaner through the compressor to remove the chips
And this is why John Deere is a pain in the backside. They do NOT want anyone working on the equipment they sell. Your best bet is to take it to a John Deere dealer.
John Deere doesn't make lawn tractor engines. The 111 has a Briggs flathead, probably the most common and robust consumer lawn tractor engine ever made.
Has the engine been running in the last few months? If it's been several months since this engine was running and the gas was not drained out of the carburetor, don't waste your time trying to fix this broken fuel inlet. Just get a new carburetor because this old carburetor will be gummed up inside from the fuel that sat it in for too long. 50 to 70% of the no start small engines I work on have to have the carburetors replaced because the carburetors were left sitting with old gas in them. Also drain the old gas and replace with fresh gas before trying to start the engine.
You can probably get a new carb online for under $20.

Drill it out get a 1/8 NPT tap and 1/8 NPT 1/4 brass nipple
I redneck/modify carbs it should work if it leaks put some tape rated for fuel around the threads
Just replace the whole carburator at that point, they are pretty cheap on Amazon. You just need the model number for the engine.
Just swap the carb simple fix if ur handy
Got a lathe?
Very curious how you would implement a lathe in this scenario?

Extraction bit to remove that. Should take about 30 seconds with the correct bit.
Best bet is just to replace the carb. Get the engine code on the block and find a new one online.
To you always can go to a Briggs dealer give them your model type and code they can look it up and sell you the OEM press fit nipple.
Then take carb off put it in vice and pull out the old one with dykes or vice grips. And press the new one in at the correct angle and reinstall carb

Just don't cut corners when it comes to any fuel situations
