TL;DR; all your analogies are less extreme than the claimed observation because they don't violate the principle that physical laws apply uniformly throughout space/time.
Theory or data/observation is a sort of layered thing. The lowest data level is the data that the Webb or whatever telescope gets, then you have the theory that what's being represented in galaxies and you have all suppositions of standard cosmology and in that you have a posited theory that galaxies as viewed from earth rotate in a "given direction".
The thing about this theory/observation/whatever is that it's a pattern that, if true, would only be visible on earth (or in vanishingly small area relative to the claimed area of the pattern). If such a thing were happening, it wouldn't just contradict current physical laws. It would contradict the paradigm science has had since Newton that physical laws apply uniformly throughout the cosmos and especially that the earth isn't the "center" of the universe. The observation of continents fitting together or violations of parity conservation aren't analogous because they involve things that can be meaningfully observed anywhere.
All this is to say "extraordinary claims require extraordinary evidence". As far as investigating. I could or someone could, spend the effort needed to investigate this. But science actually should have one level of claim+evidence that's "interesting, let's investigate" and another that's "oh dear, that's really crank stuff and you'd need to truly vast evidence before I'd even look". Other science would be overwhelm by bullshit.
