Yes. I don't think this formulation of 9ball is solvable in less than 9 weighings because it doesn't allow you to weigh groups of balls. A set of balls is not an object, so it can't be put on the left or right side of the scale
If I was put in place of the LLM I legitimately couldn't tell if the intended solution is to ignore the wording and solve 9balls, or if this is a trick question to check if I spew out a memorized answer without considering the actual wording of the problem
