I now have a sign that Funko chase variants exist in physical stores and there's probably some conspiracy behind the scenes that prevents them from hitting the shelves.
I scored a Chase What It Sounds Like Rumi, out on display, at Claire's.
I think I was able to find her because Claire's does not care about Funko Pops at all. They don't specialize in these collectibles and don't even have a dedicated section. This was the only Pop line in the entire store and they were only one layer on one of those round shelves full of KPDH bric-a-brac. They don't know the weird conspiracy rule telling them to hoard the Chases.
Besides this miraculous Chase find, Claire's is the worst place to shop for Funkos, as they're $20 as opposed to the usual $15-$16. This wasn't a Chase upcharge either, they were all that price.
