So, I don't really know what's up with the Tel Aviv thing. I think pretty much every story I have seen about this gets one important thing wrong though. Look at this MAGA heat map:

I'm almost sure that what you're seeing there is residential proxies. It didn't completely make sense to me that so much was centered in India (and also that we see random other countries that aren't all that geopolitically active featured in the data). Seeing the map makes it obvious (to me) though: Someone is buying up proxy services from places where they can be had for cheap, and then running their fake accounts through those proxies.

I don't think we actually know where the call is coming from, although the geographic distribution and the fact that some of them showed in Russia represents a strong hint.
