Maybe there's some conflict of terminology here. But as I understand it converting SQL query into a set of opcodes representing all operations needed to execute the query and then executing these opcodes is not interpreting, it's parsing. Interpreting is more related to some full-blown execution languages like python, perl, javascript or something like that. These languages indeed require some technologies like JIT. But they are not applicable to SQL. Maybe only to PL/SQL-like language, but it doesn't exist in SQLite.
