Is there any way to cut and cap inch and a quarter PVC water pipe with 60 PSI in it without shutting it off?

What about a sharkbite type cap? Gonna be pretty tough to press that cap on with 60psi trying to push it off! Definitely gonna get really wet too.
What about a sharkbite ball valve and have the valve open while you push it on and then close it once you have it properly seated?

You could use a "freeze Seal", that will require a considerable amount liquid gas like CO2 or Nitrogen to freeze the water in the line.
I have seen it done at facilities that have Nuclear Reactors.

Some plumbers have the pipe freeze kits for just an occasion

I was shown by a plumber that only does underground work on an emergency repair. you need a ball valve with a pvc slip fitting attached.
You need a can of Christy's Red Hot and Blue PVC glue
Leave the ball valve open, put a substantial coat of glue on the pipe after roughing it up with sand paper and the same for the inside of the slip fitting. Work quickly as the glue sets fairly quick. Push the fitting on , twist a little and hold in place for 3-4 minutes and then let it be with the ball valve open for about 10 minutes and then close the valve.
It is messy (water/mud etc) but it works. I worked in a mobile home park that you had to shut the whole park down for a leak. With over 300 homes that was not an option so I have done it many times.

if you freeze PVC won't it crack?

Fernco can't handle pressure. It would pop immediately
I bought an acre and a quarter adjacent to my acre and a quarter. It was split off of a 2.5 acre parcel that was owned by a guy who drilled wells. Both parcels had wells on them, and they were connected together. The guy I bought them from has a niece living there, and her husband is a jackass. It is time to split the wells plumbing apart, but there are no valves. I put valves on my end, so I can shut that off.
I was just hoping to not have to deal with the jackass, cut it, jump a valve on it, and be done. His system needs to get turned off, and the pressure tank drained, so that there is no pressure, then I can cut it and put a valve in.

Unfortunately jackass contact will be required.

Like Thunderalley says, this is the only way.

If you own it there is an easy solution. Inform the niece that you need to do a repair on the well, go over, shut it off and cut and cap the pipe. Have caps to cap both ends so if you ever want to use that pipe again it is clean.
I'm confused...
Do you own the well?
Do you own the property the jackass lives at?
Seems like a pretty simple solution if you own everything. If it's his well that you are feeding from it's still simple but requires a little more interaction.

I think personally I would pay a plumber whatever it takes to do the job and let the neighbors know that he will be doing it. That way there is no possibility they blame you for any future issues etc.
Either that or get in touch with the guy who actually owns the house and ask him to let his Niece know what you are going to do.

To someone that has never done this before, opening a 1.25" line under 60psi of water pressure is going to feel like an absolute catastrophe that they have zero chance of controlling if they can't get the fitting on and glued.
You're still cutting the pipe tied to his well, right?
I assume his pipe/well will be under pressure?

Having nicked a 1" pvc line that was under pressure it was absolutely shocking to me how much and how fast that water came out. I really wouldn't want to try to cut and cap a line with pressure...

If you are wanting to plug a PVC line turn off the air compressor first

All wells I have seen had pressure gauges at the tank
I'd agree. I know a fire sprinkler puts out a ton of water and it's not even close to 1 1/4".
Is that the tank pressure or the well pressure?

Water pressure while running. Tanks (in my experience) have a Schrader vlve to check them since you have to shutoff and drain to accurately measure them

Just use a compression fitting intended for this purpose. You will get wet but not nearly as wet as if you were cutting into a 6" pressure line. https://www.plumbingsupply.com/pdf/spears-griploc-coupling-install-instructions.pdf
