I had to Google this because I thought you were correct and I found it interesting. However till is the same as 'til, til and until. They are synonyms of till. There is the verb that means to work by plowing, sowing and raising crops. There is the noun that is the money drawer at the store. As well as the noun use of unstratified glacial drift consisting of clay, sand, gravel, and boulders intermingled. There are many uses. So your correction is wrong.

Are you using the dictionary that defines Literally as Figuratively?
Remember, dictionaries show trends. They’re a popularity contest and, like Mr Trump, something can be popular and still very wrong.
