I actually don't think the reason is that they are easier than other open math problems. I think it's more that they are "elementary" in the sense that the problems usually don't require a huge amount of domain knowledge to state.

The Collatz conjecture can be stated using basic arithmetic, yet LLMs have not been able to solve it.

		I agree it's easier than Collatz. I just mean I am not sure it's much easier than many currently open questions which are less famous but need more machinery.

		That is also one of the hardest problems.
