Not really 0-8,
I experienced one encounter with severe turbulence on a 767-300, and while we experience some erratic airspeed info, just like LOT, it returned to normal after the event stopped.
I will add that we were also unable to maintain altitude, and descended. All ended well without injuries. The yoke, thrust levers and flight controls behaved normally, and even though not a single digit on any instrument was readable due to the shaking, the blue above/brown below on the ADI worked just fine. I don't remember the EEC lights, nor cared to look at anything on the overhead panel during the event.
Ask yourself if we would have ended up in some other flight control law or had many more blinking lights and distracting warning bells, alerts or tones had we been in manufaturer "A"'s aircraft (I don't know)
