I would spray it with an equal mixture of acetone and ATF several times over a day or so and try with an "easy out" bolt extractor. And try heat later if that does not work.

+1 on the heat. I'd try 20-30 seconds with a torch.

The problem is that the thread is tapered and jammed.
You can't heat this as much as necessary...

Use a small saw blade for metal that fits into the hole (we call it 'Puck saw blade' in Germany, ) and cut the tread down to the bottom.
Maybe you have to do this on the opposite side, too.
But you will now be able to loosen the whole threated tube by driving in a solid steel needle between thread in the head / threated tube.
Take care not to harm the thread more than necessary - you will have to use a good sealer afterwards.
