This is a mildly late response so I apologise. I think we're getting to the stage now where we're very unlikely to find leather goods in exotic skins, mainly because of wider animals rights activism.
I'm not too sure about other places but the trade of exotic skins is very heavily regulated in the UK and the EU, with some member states needing you to have import permits for crocodile skin. It makes sense because the illegal exotic skin trade is difficult to regulate and there is definitely the ethical question of using the skins of endangered animals.
This regulation has sort of spread to even legal skins. I remember eyeing an ostrich skin bag from Longchamp, but the bag had to have been at least 20 years old. Even Saks Potts, who blew up a few years bag for their fur trim coats, stopped using fox fur in 2021 in favour for shearling fur. Virtually all of my mink, sable, and ostrich items are vintage because of how difficult they are to find brand new.
They're definitely out there in the realms of Vestiaire, Poshmark and even Vinted. It might be also worth shopping around in the Asian market, since their regulations on exotic skins might not be so tight. But it does take a bit of due diligence, and it seems like most fashion houses are quickly phasing them out.
