Short answer: nope.
There was a Familia LSD transmission that was super-rare in JDM-land, but it required special axles to fit it and those were even harder to find than the transmission itself. So cost of locating one + axles + freight across the Pacific, etc.. $$$ and it's still going to get walked over by a modern LSD.
We're lucky that the MFactory is available, before then it was either a Kaaz LSD ($$$$) or modifying one from a MSProtege (Also $$$$, and unreliable) and modifying the transmission to fit. Neither were good options.
There's the Phantom Grip (Phantom "Slip") that's hotly debated whether or not it actually works, it's not a real LSD by any means. There has been more than one instance where it was the direct cause of a differential failure in a G-series so I'm not going to recommend it.
How much power are you making? If traction/torque steer is an issue - invest in a quality alignment & some wider, stickier front tires. We have equal length axles already to help mitigate torque steer, if it's an issue things may be worn out.
Other things to help reduce torque steer:
urethane lower control arm bushings
front strut tower bar
Strut/spring work
