I have no idea what supports or does not support your CIA argument, but concern about Modi is newer even than concern about the rise of the BJP and Hindu nationalism. And that concern isn't just international.
Do a google news search for 'narendra modi site:www.theguardian.com' for example, sort by date, and you will see stories going back to at least 2019, and that is just the 30 pages result limit.
Do an advanced date search, key in a range, and you can easily find criticism of Modi's populism and the BJP's Hindu nationalism going back to 2010.
There are more than 40 pages of articles on The Guardian's site for the subject of Modi alone:

Here's an article from 2010 talking about Modi's involvement in riots in Gujarat when he was governor there:

Here's an article from 2003:

I don't think I need provide more evidence?
In the USA, criticism of Modi admittedly is pretty spotty, but that's more to do with the abject failure of US journalism to consider anything beyond its borders until there's an easily quantified or enumerated crisis.
But I am fairly sure if you pick a US newspaper and do a similar search you will find similar criticism.
