> The ability to identify that there isn't a simple closed form result is actually a key component of reasoning.

If that's the case, then most humans alive would fail to meet this threshold. Finding a general solution to a specific problem, and identifying whether or not there exist a closed-form solution, and even knowing these terms, are skills you're taught in higher education, and even the people who went through it are prone to forget all this unless they're applying those skills regularly in their life, which is a function of specific occupations.
