Correct. http://tilestache.org/doc/TileStache.MBTiles.html

It can serve up an existing MBTiles file. But according to the docs, it 
will not save tiles to a MBTiles file -- you need an existing MBTiles 
file, or can use tilestache-seed to create one.

This seems independent of your MBTiles question. TileStache and other 
map servers probably won't get involved with loading the content of your 
map and then creating a PDF.

Check out some of the resources here:
    http://trac.osgeo.org/openlayers/wiki/Printing

Our current favorite method is wkhtmltopdf. You basically write a new 
page using JavaScript and OpenLayers as usual, have it set the map's 
zoom and center and basemap -- so that when the page opens it's showing 
exactly the map you want. Dump the HTML to a file, have wkhtmltopdf 
convert the HTML file to a PDF (yes, wkhtmltopdf speaks JavaScript, even 
jQuery, Bing Maps, and OpenLayers). Really slick.
