Repairing lifeline connection

I highly recommend you go with a synthetic line. Dyneema is a very good choice!
You don't need the super high quality stuff for a life line. That stuff is generally for standing rigging and applications that require tighter engineering controls. And the price reflects that.
A life line can use the budget stuff readily available on Amazon and other budget friendly sources. Look for synthetic winch line.
Plus the big advantage is it's user friendly when it comes to service and maintenance.
I always prefer the "Do it myself" options.

This looks like the piece I need unless I can reuse the one I have with new lifeline wire.

LOOS Wire Rope Clevis Fitting: 1/8 in Compatible Rope Dia, Stainless Steel, Fork End

Yes, that looks roughly like the right part. No, you won’t be able to reuse the existing one, because when it’s installed it gets permanently compressed around the wire. The bigger problem you’ll have is that to install an end like that you’ll need to cut all the bad/untwisted wire off, and then use a specialty swage tool to fasten the new end on. My guess is once you cut off the bad wire section you won’t have enough wire left to span the length of the boat. Even if you did, I probably wouldn’t trust the rest of that wire seeing how the end failed.

Dyneema is not a bad option. It’s definitely easier to DIY. Just be careful that there are no hard chafe spots like in the stanchions. If there are you’ll need to add thimbles to make sure the dyneema doesn’t get cut.

Take to your local rigging shop or take it to West Marine and tell them to make you a new one, they will send it to their nearest store with rigging services.

EXCELLENT POINT!
Yes! Debur EVERYTHING!
I'd use a single cutter counter sink tool to lightly chamfer both ends of the hole through each station.
And perhaps install a piece of adhesive lined heat shink at each stantion. Just as chafe protection and an early warning indicator to expose any chafing issues / spots.
I don't have life lines.... I'm far too clumsy for that.....they tend to do more to trip me than anything else....

I would definitely replace the lifelines altogether.

Or, get rid of them altogether. I'm 100% on board with @Captain Grey Beard on that.

For Dynema, you could always do a whoopie sling to make the adjustments, then sew it where you like the final size and cut the tail, would look cleaner, or have the whoopie at the bow end and just tie off the tail to make it look nice to keep the adjustability.
Keep in mind that being adjustable would be better in the long run, would give you room to cut an end if needed!
Very easy to work with, very basic and cheap tools needed.

I like the dyneema idea but every example Or online looks very ad-hoc / messy. Maybe there is a middle ground combining dyneema and turnbuckles.

One end should be very easy to make neat and clean with a splice. For the other end either do the sling like Fred mentioned, or you could get a fitting like Tubular Turnbuckle with Splice end - LS-2900. (That’s just one example; there are quite a few types)

I'm not a fan of dyneema lifelines, because in the long run I don't believe they are as economical as people want to believe they are.

Lifelines are pretty inexpensive to replace. There is no need to replace turnbuckles barrels unless they have been stripped or otherwise compromised. Use bare wire instead of vinyl coated, bare wire is cheaper and safer.

Take the life lines off, label them and send them to a rigger who can reproduce them in short order. A swaged stud will run about $15 and $15 to swage it onto the wire. ¼" 7x7 wire will run under $3 a foot.

I've used RiggingOnly.com to replace all the rigging and have been pleased with their work, speed, and price.

To my knowledge, Catalina did not go to open body turnbuckles until the new design. That in itself is a compelling reason to fully replace the life lines.
