Replace exterior faucet

[JohnON]

Hello,
I'm looking to replace my exterior faucet and noticed the pipe is twisted. I am new to doing any plumbing but am trying to learn so your help is appreciated.
I am looking to get a new faucet and Teflon tape to replace what I currently have. Since I noticed the twisted pipe I am concerned when I twist to remove what is currently in place I may hit an issue I wasn't expecting.

Am I able to just twist the current pipe until it comes off?
Do I need to remove the screw and valve prior to removing the whole unit. The screw is stripped but I could drill it out.

Any thoughts on your end? The house & piping likely has never been changed since built in 1979. I was feeling confident until I saw how twisted the pipe was. We are replacing because it leaks when turned on from the attachment valve.

It looks like some gray back there behind the valve, perhaps the valve was soldered on. If that is the case, you may as well go under the home and cut the back in the crawl area and couple on new pipe to a new valve. Twisting what you have will cause more damage behind the panel there.
They do make a Sharkbite fitting which is a push connect for those without a torch, flux and solder.

The copper pipe inside the wall looks twisted already.
