I was wondering if there is a nice IF NOT EXISTS for checking columns and indexes in SQLite, or do I need to bring back the entire database schema and validate against that?

Yes the following syntax is supported in sqlite:
CREATE INDEX IF NOT EXISTS ...See here
To check existence of a column you could simply try to do something like
SELECT col from TABLE. If it does not return an error your table containscol.
