Because He is not interested in asking Whether the Grammar is $LL(1)$ Or Not. Of course, The Grammar is Not $LL(1)$ because of Left Recursion. But Why do we say that "The Grammar is Not $LL(1)$ because of Left Recursion" ?
That's because When you make the Predictive Parser table for this Grammar, Some Cell will definitely contain Multiple Entries Which makes it Non-$LL(1)$. But in the Question He wants to ask about what Entries the respective cells will contain.
And One More thing, When Some Grammar is given to you and it does contain Left Recursion, We do not remove left recursion from it and afterwards decide it is $LL(1)$ or not. We decide it for the given Grammar.. Without changing it.
