I don't think Erdős would consider it all that disrespectful as his Wikipedia entry quotes 'the "ő," often (even in Erdos's own papers) by mistake or out of typographical necessity replaced by "ö,".'

For example, at https://web.archive.org/web/20051015141515/http://ecp6.jussi... you see he used "Paul Erdös".

The same for his paper at https://web.archive.org/web/20120324221556/http://www.amt.ed... where the mathematics journal's typesetting clearly supports á, ó, and ö.
