Inspection failed for bonding locknut, NEC code needed please

I can you show several photos of PVC pulling out of meter enclosures that are only 4' in length

Most of the problem I see with PVC pulling down/out of the meter base is caused by poor installation. The sweep is put on but doesn't touch the bottom of the trench. I always either shovel dirt under it or put a brick, or rock under the sweep to support it. That doesn't prevent earth movement, but stops gravity from adding to the problem.

I went to repair one where the PVC had dropped down. The HO just couldn't understand why it dropped down. He had a sidewalk poured right over the UG conduit & sweep.

But an expansion fitting would prevent it from happening per 352.44

I'd be way more concerned with that SER cable that does not 'closely follow the surface' than a PVC expansion fitting. I have never used a PVC expansion fitting into a residential meter, but I also would not flop SER cable across a conduit rack within a foot of grade.
If it were me I would use PVC for the whole job no bond bushing needed.
Moving a FIOS box is simple apprentice work no excuse for that.

I generally try to have the elbow at bottom of trench and in either undisturbed soil or compacted soil that shouldn't settle and deep enough to be below frost line. Seldom to never had a failure with no expansion fitting if done that way and short enough length that thermal expansion is not an issue either.

I have seen cases with expansion fittings where the conduit pulled down as the fill settled and pulled conductor enough to damage meter socket terminal. Yes you can leave service loop in conductor but at same time there is only so much room in most individual meter enclosures plus 200+ amp conductors don't necessarily flex very easily, and what flex they may have still puts strain on the terminal, which is why we bend conductor then land in the terminal vs land conductor in the terminal then bend it using the terminal to gain some leverage.
