The intriguing thing to me is that this length of pipe will experience quite an increase in surge pressure, regardless of whether it has elevation changes. The energy of the flowing water causes this when the flow is stopped at the outlet end. This pressure can be several times the stagnant pressure. That's a lot of fatigue cycles to endure. So, if replacing this pipe consider a pressure tank which will help this situation, too.

I assume the OP isn’t using the 2” line at capacity and reduced it to a 3/4” tap at the end. That would make the velocity in the 2” line fairly slow and drastically lower the water hammer effect.
Why not use a piece of gasket to gasket pcv coupling. Or use two if needed and cut out a big enough section if to bend the new straight piece in.

For my waterline, which is only 800 feet long, they water department provided me with metal elbows for the turns. They did not want the pipe to bend, so I have several 45's in my run.
This was 20 years ago, and my memory of what they looked like isn't great. I remember there was a lot of bolts to hold them together, and they were very heavy.
Since my pipe is gasketed, and slides in and out as the ground expands and contracts, they had me install about a dozen sacks of concrete at the end of the line to stop the pipe from moving more than it should. Then they taped into the side of my pipe for the meter.
When I ran my waterline into my land, I talked to the guy in charge of the Water Department. He told me what he wanted me to use, and then he sold it to me at their cost. He wanted me to do it his way, which I agreed with. They know more than I do, so I did all the labor, but with their materials.

My question is why would someone make a 180 degree bend in 2" PVC pipe vs a series of 45 degree sections? That's your root cause.
