Everyone did have to get “tested” but it was one of those that come back always “negative” was my understanding from some on the flight.
I don't know about always coming back negative. Based on what I was told by someone who was on the flight, it was rather superficial. That being said, IME the tests administered upon landing in TLV are also very superficial.
But that is totally irrelevant. Supposedly exposure might have occurred in Almaty, with people from all over the world in attendance and large crowds coming together. A test administered in the US prior to departure would do nothing to detect a virus that was picked up in Almaty from someone arriving from elsewhere. And no regulations were skirted. A PCR test was conducted 3 days prior to departure from Almaty back to the US!
