I think this is simply not true in my experience…

However when I visit my in laws on the Florida coast, they have “turtle lights” which are required by law to not confuse hatchlings when they first emerge from the sand. These are an orange hue and I noticed that they have way less swarming bugs than a typical street light. So I would say certain frequencies definitely confuse bugs less, but LEDs as a whole seems too broad a category to make that statement.
