This is what I would use. It's pretty commonly available from various manufacturers.There are a variety of tie rod separating tools that would work on that. Just do a Google search.
Powerbuilt Small Tie Rod Puller-648692 - The Home Depot
A pulley puller. Two or three jaw set.
Before setting the puller, hold the head of a 3# hammer against one rounded side of the broken piece and hit the other rounded side 2-3 times w medium force. That will jar the taper a bit making it easier to pull. Doesn't touch the boot.

I learned that technique working on Fiat automobiles in the seventies! The "BFH" method.I have had them come apart using the hammer method without even using a puller or fork (an old trick I learned years ago while working in a wrecking yard).
X2 (or more). I have a pickle fork but the hammer method works when you can get to them easily and get a sharp swing with a hammer.X-3 on using a backup hammer on one side and hit the other side 180*.
I have never used a pickle fork to get these apart, just the 2 hammer method on tie rods, ball joints and Pittman arms.
Use a 3 lb sledge hammer for back up and get solid hits on front side.
