On panel or not, i repeat Mihawk has never clashed with a top tier.. Kaido and Shanks situation has no conditions.. Shanks Bounty was 1 Billion when they dueled and he lost his arm after which is the main reason Mihawk doesn't want to settle things with Shanks..
It's not that Whitebeard called their duels legendary, it's that in this era there was so few Legendary events happening that now Shanks and Mihawk duels were deemed legends when it wouldn't have been in the time of Roger and Rocks..
No Cut touch =/= No cut no touch
No cut touch = Swordsmanship
No cut no touch = Not Swordsmanship

Nobody would consider their duel legendary if they weren't top tier.
