D&D didn't even have a (main product line) sorcerer class until 3rd edition. What Lina's doing throughout the series has no connection to Vancian magic which was overwhelmingly the D&D magical mode at the time. (Her powers actually best align with Druid or some of the other shamanic classes which were... a long ways off, in D&D at least. She can in fact heal.) Your underestimation of Japanese knowledge of English/European fantasy is verging on offensive. Sure, D&D inspired Slayers, but so did other stuff. It's no obvious system-specific replay like Lodoss War.
