Greetings Kelbear63 and welcome to the community!
Kelbear you are on the right track already.
Adding a vapor barrier under the kitchen floor will create a friendly environment for most subfloor materials we have available on the market today with exception of particle board.
Dry rot is a weakening of the wood caused by the one of several species of fungus. Dry rot fungus has the ability of transporting water from wet areas to dry areas, allowing the fungus to grow in dry wood.
Water is most likely coming from the crawlspace or a basement with heightened moisture content. Adding a vapor barrier will eliminate moisture permeability from the areas below kitchen floor.
The product I would recommend for your application would be a Dry Ply subfloor panel. Dry Ply panels have a water- repellant coating to provide weather protection during the exposed construction cycle.
Another option would be to use pressure treated plywood, pressure treated plywood is chemically treated to resist rot and decay. Any of these products are extremely durable to the exposed weather conditions and I can see them performing well in your application.
Hope that helps.
