I will tell you why it is not.
Intelligence is understanding low level stuff and using it to reason about and understand high level stuff.
When LLMs demonstrate "highly intelligent" behavior, like solving a complex math problem (high level stuff), but also simultaneously demonstrate that it does not know how to count (low level stuff that the high level stuff depends on), it proves that it is not actually "intelligent" and is not "reasoning".
Do you have any rational objection to the definition? If you don't have, then I am afraid that you don't have a point.
