I actually tried that and ended up chipping a piece off and that's why it's leaking oil. I could try that again or maybe weld something to it with an aluminum welder.

These are a PAIN in the ***. I've been through this a couple times, though LOL:
With the two I had to force out, the hex area kept stripping and disintegrating until pretty much round. I don't even know if these are aluminum. They are super brittle. Like magnesium? Anyway.
If I remember right: To get mine off, I had to drill the center out. It's really thin so be CAREFUL: you will break through in no time. I mean like a couple mm thin. I then forced a hex socket (see pic below) into the new hole and was able to break the cap loose Be careful, there's an oil passage behind it. It's thin and brittle enough to maybe drill a hole or two then just knock it out with a screwdriver and hammer?
The above idea is good too. If you can grind a notch, then use tap on a chisel while turning it, that may work.
It all depends on how tight it's put in.
Once you get it off and you go to put the new one in, get the correct size hex head SOCKET. Do not use a regular allen wrench. The hole is shallow, you will get in there crooked, and it will strip; eventually. I believe it's 14mm, as you mention:
Take a grinder and grind it flat. Get rid of the chamfer (see arrrow). You want this thing to sit as flat and far in as you can get it.
Torque to spec. More importantly: use this tool to remove the plug. While using a ratchet, you can use your free hand to really hold in place. Once I've removed a plug two or three times, I replace it with another, if it's looking shady. The cost is worth not having the trouble you are in right now.
You can get away with putting in a new cap and using a regular allen wrench, but it's risky and seems to eventually fail. Ultimately up to you. The sockets are cheap though.
Good luck and be patient.

Use a sharp chizel and tap it in a left rotating manner.
Drilling the center is gonna put metal flakes in the cvvt.
They arent that tight. You likely used wrong size.

Im not sure if this will work but just throwing this out there as Ive done a similar thing in the past albeit not on this particular part. Try using a torx bit that is slightly too large and hammer it on there and maybe that will give you enough bite to get the bolt out.

Chisel method works for me every time when they strip.
