Yes, along with the refrigerant lines going through the wall behind the air
handler there is also a drain line. Most units also run the fan a bit slower
to allow for more humidity removal.

There is still a drain that either goes outside or into an interior drain
somewhere....

Yes, there's typically a drain line in with the refrigerant lines. The
installation manuals for many models are available online. Here's one
example:

You may have to paste that link back together.

I've installed a couple of these. Yes, it needs a drain. The drain tube goes
out the same direction as the freon tubing, in most cases.

Thanks for everyone who has replied. Now I understand that there is a
drain tube going outdoor from the indoor unit of a ductless split
system. This makes sense to me now.
