That's an invalid syntax for ogr2ogr. Only accept one only datasource.
In your example you could just move the 2 shapefiles into a new directory
"blabla"

and then

ogr2ogr -f PDF trentino.pdf blabla


Another (more complicated) option would be to use a OGR VRT that would reference
to your various input layers.

Yes, the PDF driver doesn't support update/append mode.

OGR_DATASOURCE not supported in the OGR driver, only the raster driver
