No, but pilots already are bad sources of data, then filter that through a passenger and who knows if that actually happened. Lots of pilots claim stuff happened that didn't once the data was reviewed.
I was involved in an investigation were the aircraft went off the runway, neither pilot realized the airbrakes were never deployed. They announced to the aircraft that the brakes failed and they and no braking power. A similar conversation was caught on the cockpit voice recorder. They were convinced the plane was broken. What actually happened is without airbrakes, there is almost no weight on the tires so the antiskid system won't apply much power to prevent skidding. Just like ABS in a car on ice.
On the 787, there was an airworthiness directive (AD, which are required maintenance) that came out years ago that said the aircraft had to be rebooted every 20 days or the system could randomly reboot in flight. It's possible that Latam failed to do that. Not exactly sure what that would do in flight, but it probably runs through a built in test (BIT) check that moves flight controls.
