This sounds like a process, not an engineering problem. The plane had known faulty sensors, and the pilots didn't know about crucial operating features of the plane.
No amount of engineering will save you from this, if you add more they'll maintain it less so that'll fail instead.
The Emergency Airworthiness Directive issued after Lion Air 610 crash was, in summary, "Pilots, remember that there is a runaway stabilizer QRH response and pilots should follow that when indicated."
If you're arguing that the pilots didn't know about the possibility of runaway trim, I don't find that very likely. If you're arguing that they didn't specifically know that MCAS could cause runaway trim, I probably agree but think it's irrelevant as the response to runaway trim is not to diagnose or draw the system diagram of the fault, but rather to simply stop the fault, which the stock 737 checklist would have accomplished, if followed.
