I have not heard of anyone suggesting to have energy drinks specifically when ketones are present, and I don't how see it could possibly help (that is, how the caffeine/taurine/whatever they put in there would help).
If the body's energy requirements cannot be met by glucose (i.e. carbohydrates eaten) then it switches to using other sources, and this results in the release of ketones.*
Having a sugary drink (or a glucose IV if you're in a hospital) - such as an energy drink, but not a diet one - combined with insulin (injected or IV) will therefore get rid of ketones.
* There is debate over whether that's necessarily a bad thing; whilst everyone agrees that diabetic ketoacidocis (DKA) is dangerous there are some that think that ketosis is, in fact, healthier than our regular diet.
