Check grammar for LL(1)?
If the question is, "Is this grammar LL(1)?", then the answer is "No".

If the question is, "Can this grammar be made LL(1)", then by all means remove the left-recursion.

The distinction is important because removing left-recursion does not preserve derivation order, so the left-recursion-eliminated grammar produces different parse trees. If it is being used to parse, it is not the same grammar.
