And after clicking all the dialog boxes, you actually get the document processed correctly? I wouldn't think you would, since the theorem environment simply isn't defined in the koma-script book class, and I've run a short test here with just one included document. (I've attached the test files.) Even if I include the AMS math packages, I get the LaTeX error: Environment theorem undefined. The problem isn't that the LyX GUI isn't allowing you to enter the theorem environment in koma-script: It's that the theorem environment doesn't exist in koma-script.
LyX is trying to warn you about exactly this problem: When you include the Book(AMS) documents in the main Book(koma-script) documents, the class of the included document is irrelevant. The class has already been set by the main document, and it cannot be changed mid-stream: It's a document-global property. LyX will allow you to create and edit the included documents with whatever class you wish, since it doesn't know they're included documents. It will only complain when you try to process the master document. (Maybe LyX should complain when you try to include a document with a different class?) So the solution you mention isn't a solution to your problem: It won't work. If you want to use Book(koma-script) for the main document, then the only way you can use the theorem environment is to define it yourself in the preamble. (Maybe you've already done so. If so, see below.) If you're using other environments from the AMS book class, such as proof, then those will have to be defined, too. Maybe someone somewhere along the way wrote a style file to do this: Check CTAN. But another, simpler option may be to use the AMS book class and then make whatever changes you need to make to it (using packages like titlesec, titletoc, and tocloft, if there are issues about how section headings and the like are set). Now maybe you've already figured out this issue and just want to know how to be allowed to enter the theorem environment you've already defined. In that case, the answer is to modify the koma-script book layout. That's in scrbook.layout, and you should be able simply to cut-and-paste from amsbook.layout to get whatever other environments you want into the new layout. You will also want to change the second line (the one you're warned not to change!) in your local copy, so you can use both it and the original koma-script book layout.
