I believe it will be easy for Boeing to document the proper procedures were in place and the training was appropriate. The burden will fall on mechanic error and whoever signed off the paperwork saying these procedures were followed. Boeing’s liability will be limited.
Alaska Airlines will be similarly situated.
In the past, the reason so many aircraft accidents were labeled “Pilot Error”was to limit liability of the company. That has shifted when the deep pockets were pursued over nit-picky procedural errors. The companies responded by having so much of there manuals written in legalese. That’s great for the trial lawyers, but a pain for the everyday user.

“whoever signed off the paperwork saying these procedures were followed”
I think your referring to quality control, and yes more than likely the documentation is all electronic which means it should be available at virtually the push of a button.
However, last I heard was Boeing was unresponsive to turning over that data to the NTSB.
