Frank, there are some great low carb, pressure cooker site on the interweb.
I'm a relatively new covert to pressure cooker (IP) cooking (my OH has used a pressure cooker since before I knew him,
but it scared me - all that hissing!), having bought an Instant Pot last Black Friday (and evangelised so much
@Brunneria bought one), so I tend to look out for bloggers/recipes using the IP. Fortunately, one of my favourite food bloggers is a massive IP user/IP cookery book author. Her food is largely LC.

I also like I Breathe I'm Hungry, who is a strong low carber, but also has an IP, so some of her recipes utilise it. Of course, having been using a pressure cooker for years, you can probably convert your recipes without too much guidance.
