Elisabeth wasn't just the match that set it off, the whole point of BAS was that she was the one that ensured (good ending) Bioshock ended the way it did, with Jack getting to Rapture and saving all the Little Sisters Without Elizabeth we would eventually have had the civil war, just without Jack crashing in at the end.
There’s some dialogue from Splicers in 2 that references the ambiguity of it. But, also, I don’t know if you’ve played Infinite’s DLC or not, but the end of Burial at Sea 2 seems to imply that the good ending is canon.
