I’m not aware of any universal compatibility chart maintained across multiple brands.
For this case however, from what I understand Ltwoo uses the same (or very similar) pull ratio to Shimano 2:1 (actually about 1.7:1). This is the ratio used for Shimano’s road groups up to 10 speed and their mountain groups up to 9-speed.
Unfortunately, if you’re looking for a modern mountain derailleur with large capacity and clutch, it doesn’t leave you with many good options.
I’ve been hearing rumours of them considering over-regulating mountain bike racing; limiting suspension travel for XC and Enduro, etc.
Forcing the turned in brake hoods on a minimum width bar (40cm) seems quite silly here too. Straighter hoods on a 38 or 36 cm bar would be better all around.
