(I have control over both generation & lldb api) For example I have an array type that from the LLDB api looks like a pointer to it's sub type. There's a "length" field before it, and from the LLDB side I Want to look at the "length" and use it to display the sub entries, but then I have to store & know it from both side.

If it is a custom array type, you should look into writing a synthetic formatter for it so it can act just like an array should. We have many examples for std::vector, NSArray and more. Synthetic formatters are little python plug-ins that can create child objects for a given type, and also provide a summary string for the main type (like "3 objects" for an array).
