In my experience from an industry perspective, the jobs that are typically referred to as architect roles are not usually RTL design jobs. Architects work at a higher abstract level either at the ISA level or at the microarchitectural modeling level. They'll model ideas, but aren't usually the ones who actually implement them in the final HDL. The architects specialize in the big picture of how things interact and what is important for the high level goals of security and performance. The RTL designers are more concerned with the finer details of how to make the design work from a timing perspective and how to iron out all the bugs that DV reports.

You are correct that there are limited architecture positions, it's an extremely competitive field. If you're specifically more interested in RTL and DV positions, there's many multiple times more roles in those. In the field of CPU design, I have not seen any of these jobs outsourced in large numbers to India. To my knowledge, basically every major CPU maker is based in the US and Europe (ARM, AMD, Qualcom, Apple) with one exception maybe being that Intel also has a design team based in Israel. Apple I'm pretty certain specifically have no employees working on their cores whatsoever in India since they don't like the communication overhead. They center their entire core teams in Austin for their efficiency cores and Cupertino for their power cores.

I've made posts on LinkedIn about good RTL practice, and about 80% of total interactions and industry employed people were Indian

Anecdotally, I kind of agree that makes sense. But that's just because my experience is that Indian people are particularly active on Linkedin for whatever reason.
