Well, I'm not sure exactly what you're looking for, as I'm mostly unaware of what's on Lezhin. (I know that Pulse and Lily Love have been published there, but that's about it.) However, if you're just looking for a buffet-style webtoon site, there's LINE's webtoon site.
Most of the content is from Korean authors, translated into english (sometimes other languages too). They've been adding a lot of content from other regions, and have some sort of publishing thing for... I guess the best word I can think of is "amateurs". In terms of yuri, the vast majority of romance is het, though it seems like they've begun working with authors of LGBTQ+ comics more often recently. Most of that is from western authors as far as I've seen (which, frankly, isn't terribly shocking, but if the country of origin bothers you somehow, there's that to consider).
If you're looking specifically for LGBTQ+ works, I highly recommend Always Human, it's very inclusive and exceedingly (maybe even excessively! :P) positive, a nice soothing read to be sure. It finished a little over half a year ago, and I miss it dearly. orz
edit: by the way, what's happening with Lezhin? It sounds alarming, especially considering that at least one of my favorite authors has their work published there.
edit 2: ah, nevermind, looked into it myself... WOW that's shitty. Just... SUPER shitty. What the fuck?
