This advise is generic to all import ploblems of this nature with other progams too.

Probably your best approach would be to look for the data forms like xml forms of the osm database (the editor JOSM can save xml for your chosen spot plus a lot of services descibed on the osm website will provide cut downs for areas and contries.

Next massage the data file with something like a text editor, spreadsheet or database progam so the essence of the data values you want in your illustrator import file are in the order you want then edit in possibly with search and replace: the necessary formating needed for your new handmade illustrator file. Its also worth looking at other import filetypes illustrator can handle to find which is the simplelest such as csv point import (if it would do this) or look at other graphic programs that output files that illustrator can import easily that themselves can import simpler filetypes to makeup than than those with illustrator.
