breaking change of list_parsers and others by introducing as_list option

[AVitg]

introducing default "as_list: bool = True," for below methods introduces a breaking and inconsistent change, as others default to False.

pls change default to old way of returning "raw api response with pageination info", or default to True everywhere.
