Why do you think 11 isn’t pronounced onety-one?

Because numbers in English aren't pronounced out loud when used as numbers, except for 11, which is traditionally called 'eleven'. 
This goes back to the Germanic origins of the English language where 11 was called 'one and one' which later morphed into the name we use today: eleven.
