Unlocking an LG Lotus

You'd have to send the phone off to be tested for compatibility before activating it on the network. Seeing as how there's no "unlock" on such a phone, nor is there an LG software you could flash onto this Sprint phone that would not include Sprint connectivity, I doubt it would fail testing. If there were a flash from LG you could obtain that works with Verizon, then you could flash the software on there and send it off for testing.
