It sounds like you need "crossover" or v-cut leggings, where it's higher in the back and cut into a dipped v in the front under the tum.
But also...I hope this doesn't make you mad but maybe leggings and/or yoga pants just aren't working? I literally own zero leggings or yoga pants. Zero.
Because they are not my friend for similar reasons. I don't need the world to see my Alfred Hitchcock lookin' self with a fuller midsection and flat booty prancing around like I don't know what flatters me. The waist typically either rolls down or feels weird, and I just don't get enough use out of them because leggings + longer top is super dated and I'm not going to do the crop top thing.
Would flat-waistband ponte pants, palazzo pants, or maybe performance pants work?
However here's some options:
Amazon, although they have a 32" inseam so you might need to get them tailored
Carbon 30 has a lot of niche, high end brands that you might not have tried yet like these
Alo yoga is a brand I didn't see you listing
I'd also look into Girlfriend Collective and Outdoor Voices as well as Torrid, although these aren't yoga pants per se
Also try Zelle--they have some interesting options
Another possibility is etsy--they often make clothing to order and they do make yoga pants and leggings.
