What do we do about potential empty lists that will be thrown into
logo-type? Make them [] or empty spaces or just ignore them? Thanks in
advance.

Although your Logo isn't supposed to be exactly the same as Berkeley Logo,
you can generally get a good idea how to answer questions like this by
trying them in Berkeley Logo.

TYPE [] doesn't type anything; therefore PRINT [] prints an empty line;
SHOW [] prints a line with [] in it.
