You can't assume that -aggio is a suffix derived from Latin -aticus in every Italian surname. For example, Maggio comes from Latin Maius 'May' and Baggio is thought to come from Celtic bagos 'oak'. As for Biag(g)i(o), of which Piag(g)i(o) is probably a variant, it comes from Latin blæsus (later blasius) 'stutterer, stammerer'.
