One example is that the charging system in the car doesn't just need to output 13+ volts... It has to also output a minimum amperage AND needs to be verified to switch into a "maintenance mode" when the battery reaches full charge because AGM batteries are extremely sensitive to overcharging.

Tech or mechanic doesn't matter your paid to fix the car so fix it and yes things are more complicated which means you have to be more rigorous in your approach. High tech isn't an excuse!!
Doesn't matter maintenance mode or other wise. The modules are there to collect data from a bunch of sensors and via the logic that is programmed into it, output a signal to provide a course of action.
That course of action in this place either seems to be a loss of voltage or a lack of fuel both of which keep the engine running. You also have a code that is linked to the fuel system that is telling you loss of voltage. Could that "logic engine" , (BCM) be broken? Could be but what about all the circuits that provide it with those inputs ?? Does the logic even work without the correct voltage --- probably not.
Few like working with electricity for the most part because you can't see it and feel it. It was the same 40 years ago!!! Real easy to turn wrenches and replace parts. Actually takes some talent and effort to trouble shoot things.
Put a known good battery in it. Clear all the codes. If the engine cranks but doesn't start it is either not getting spark or fuel. Spark is easy to check. Do the codes come back?? If it wasn't getting any fuel I suspect it would but I bet it gets fuel, starts and then dies later because the charging system isn't working correctly. That condition was also reported.
