Answer 1

This variation of the answer provided by @user1461607 ensures that any CSV values that happen to be empty strings are preserved:

WITH RECURSIVE split(value, str) AS (
      SELECT null, 'Auto,A,1234444' || ','  -- the string to be split 
      UNION ALL
      SELECT
      substr(str, 0, instr(str, ',')),
      substr(str, instr(str, ',')+1)
      FROM split WHERE str!=''
  ) SELECT value FROM split WHERE value is not NULL;

Converting a CSV line to a JSON array

Assuming the JSON1 extension has been loaded, you could use json_group_array(value) in the last line to convert the CSV to a JSON array of strings.
