I don't know yet of a tool to perform this type of conversion directly, but I think you could download and use any of these two:
http://choonchernlim.com/kmlcsv/
http://www.mchme.com/cms/
to convert the KML or KMZ to CSV, and converting from CSV to PDF or DWG is way easier ( a lot of tools are available on the Internet that let you convert CSV to PDF/DWG ).
Another way would be to install and use a virtual PDF printer that lets you create PDF documents from any kind of printable file. Just google "virtual pdf printer" and you'll find plenty.
