I suppose you could run some transfer beams from the wall or post/footing in the lower area to new piers farther back into the crawlspace - removing and eliminating the need for the existing piers.
If it is bowing, it is likely not designed or constructed properly
Also, it is about impossible to inspect a residential retaining wall.
"Well it ain't leaning so I guess it is OK for now"

Well. look at how many recalls Ford has. Their eco-boost line of engines are garbage. GM's AFM and 6.0L, Chrysler - I means it's Chrysler. Toyota replacing 100,000 Tundra engines, Honda 3.5. Nissan CVT's.

Around here, most residential involvement is due to shrinkage and swelling of underlying plastic clay soils. The only calculation I usually do is the required helical capacity. I end up putting them 5-6 ft. O.C. on most jobs. I get about $1350 total for the site visit, drawing and a follow-up...
