One other bit of possibly useful data would be to eyeball the file mod
times in the orphaned subdirectories. If they were from failed CREATE
DATABASEs then I'd expect every file in a given directory to have the
same mod time (modulo the amount of time it takes to copy the DB, which
is probably not trivial for the DB sizes you're dealing with). If you
could also correlate that to the times you saw CREATE failures then it'd
be pretty convincing that we know failed CREATEs are the issue.

Also, I would definitely urge you to update to 8.3.4. Although I'm not
seeing a mechanism for CREATE to fail to clean up like this, I'm looking
at the 8.3 branch tip code, not 8.3.0 ...
