So I'm finding a million conflicting things on the web, and it's hard enough to search for anything 3IS because mostly 2IS stuff pops up. 15 IS350 F-Sport does NOT come with LSD, correct? I've spent over 2 hours searching to avoid being that type of poster. But I've given up, I'll just ask.

You're absolutely correct.
Only the 2018 models have that option, I believe.

You can buy aftermarket and get it installed. Alternative option is to turn off the traction control completely by holding the button down for 5 seconds.

It's not the same but you can get some entertainment from it lol..
