If you must use the dub name, it's "Lita" with a "T". But "canonically", when Doug goes to the SM world, I'll be using Japanese names exclusively, so you might want to follow my usage.
In fact, I have a little passage written for DW13 that touches on this:
"Ohmygod!" Dawn screeched. "That's... That's Serena!"
"Usagi," I corrected absently. "Her name is Tsukino Usagi."
"But..." Dawn began, and at that moment the image's eyes snapped
open. It looked straight ahead, as if into some unseen camera,
and did not seem to acknowledge either of us.
"Hello, Doug-Sensei," the image of Usagi said in faintly-
accented English, and I smiled fondly at the sound of it. Usagi
could speak English perfectly without an accent -- I'd taught her
well -- but she loved the idea of sounding "exotic" to native
speakers, even ones who knew better (like yours truly). It was
one of her few concessions to a minor streak of vanity she
normally kept well suppressed. "I'm not entirely sure this will
work, but if it does, yay me." She grinned without quite looking
at me, and I suddenly felt a pang of loss. Usagi and the other
Sailor Senshi -- Makoto especially -- had been like daughters to
me.
...
Dawn looked at me with wide eyes. "You went to the Negaverse
with them!"
"Dark Kingdom. Yeah," I said.
Hm. That got heavily redacted to remove spoilers, but you see what I mean.

Then the horns kicked in...
...and my shoes began to squeak.
