I started to replace the right-center axle wheel cylinder. I found the
brake line fitting to the wheel cylinder had been rounded off. Do I need to
replace the brake line to get a new fitting? Is there enough line slack to
cut the tubing and replace the fitting?

John,
You don't have to, but there is not enough slack to pull the line and re-flare it for the new nut. Just buy a new piece of line as it will be easier.
You are an e-mail reader without a sigfile so I don't know where you are, but if you are anyplace that iron rusts I have a suggestion that will pay off in the future. On ever wheel cylinder or caliper, pull the bleed screw all the way out and put a wrap about one and an half turns of teflon tape on it. This way, when you go to use the bleeder again, it just might unscrew. The teflon tape keeps the brake fluid (that assist corrosion) from getting into the threads and the environmental moisture is also excluded. Then just be sure that all the brake bleeds have their caps and the next time you go to mess with the brakes, things will go much better.
I used to used a teflon pipe thread sealant, but the tape works better. It would be an even better idea if it were mine. Chuck Boyd brought that up years ago.

Matt,
You failed to tell John about your magic Vice Grips! Those MIGHT save him.

Is there something special about Matt's Vice Grips, or will any old pair of
big Vice Grips work?

John,
This 7" version is probably the most all-around versatile, but the 4"
version is sometimes needed for tight locations:

Yes,
When He said that the hex was blown off, I should have. - Sorry about that....
I guess I could do a link, these have been a part of my kit for so long that I don't think of them as special.
I can't find a really good link. They all take me to E-bay or Amazon and you can do better.
Search for: "ViseGrip 4LW" LW means locking wrench
That LW means it has jaws that will grip three FLATs of a blown out hex. They can grip well enough so that (one one very memorable occasion) I was able to fail a brake line nut in shear and the tool still held the hex. (I didn't get to save that wheel cylinder.)
The best deal I am finding is a Zoro.com.
The 4" should be less than 9$ and if you have to pay for shipping, get the 7" at the same time.
The 4" is tiny, but it is about the right size for brake lines and bleeder screws.
The real thing is to look for the special jaw shape.
Years ago, I bought the set of three because they looked like a good idea. I have probably only used the 10" a couple of times.

What he really needs to do, is get his hands on the neck of the person that
persisted in using the wrong tool on that fitting. Although, if that person
is of middle age or beyond, and is still rounding off brake line fittings,
re-education may be impossible. Old sloppy habits die hard. Heating/cooling
cycles combined with the correct tools and penetrating oil of your choice
usually will prevail.
