Just got my 435i last weekend and my first planned mod was the OEM LSD... only to find out it's discontinued and not a single place has it in stock, new, used, or refurbished

I remember reading a review that mentioned the extra locking on deceleration really helped with confidence under braking vs an aftermarket diff it was being compared to

Would I have luck asking a dealer? Or am I just out of luck

You can ask, but you are probably out of luck finding one from BMW.

You can post in the classifieds and try to find a used one.

You can also explore aftermarket options.

Been seeing one or 2 posts selling one not long ago but not sure if it has sold yet. As mentioned above, your best bet here is to post a WTB thread in the classified or stalk the classified section.
