Founding fathers in US perhaps left...filler gaps, to revert back 'without realising' the growing demands for use of Le Systeme Internationale d'Unites; and CGPM left scope for later review. Litre & kiloLitre are imbedded in our lives, so are cc & Metre-cube. Resolving the issue is need but NOT at the cost of further delays - especially for Time & arc-angle(length) to be brought on common platform.
CGPM can re-write the bible for symbols,units & sub-units and review in due course, while *Calendar, Time & arc-angle* draw their attention now causing to 'bridge gaps in SI', then left delibrately or otherwise!

But anyone familiar with the metric system can easily see they are the same volume/quantity.

Kilolitre violates one of the simplifying rules of SI. It causes there to be two different names (kilolitre and cubic metre) and two different symbols (k and m^3) for the same thing. Furthermore, the litre is not an SI unit (it is not coherent with other SI units), the kilolitre creates still another non-SI, non-coherent unit. The litre is already an exception to basic SI use, an exception which is sanctioned by CGPM to address the problem of not having a convenient unit with a size between the cubic centimeter (or cubic millimetre) and the cubic metre. There is no such need to introduce the kilolitre because there is already a named unit of the appropriate size, namely the cubic metre. The dubious advantage that "kL" is simpler to write than is "m^3", because it avoids the need for an exponent, is small compared to the problems of multiple names and symbols for the same unit and allowing additional exceptions to pure SI.
