All LS based engines had lifter problems, even some valve and valve spring problems too, there was just a lot more in the AFM years due to a more parts, complex design, and probably cheaper sourced parts. For trucks AFM started in 2007, and was only on the 5.3L, later it came out on the 4.3L V6, and 1500 6.2L, but never on the 4.8L or 6.0L, so don't worry about 3/4 or heavier trucks having AFM.
The newest edition of AFM is called Dynamic Fuel Management or DFM. This came out on the 2019 to current engines.

It can kill 2 cylinders, 4 cylinders or any of all 8 cylinders depending on certain loads or conditions. The newest design has brought even more types of valvetrain failures (lifters, valves, cam, and pushrods)

I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
