Ok Follow this steps and you can do it but i am 99% sure only.
Go to res-> layout folder and Right Click on it and you get a sidebar asking for what type of file you want to create
Go to -> Edit File Templates option.

Sidebar>

You will see this dialog opened. You see both options right there inside Other tab These options are LayoutResourceFile.xml and LayoutResourceFile_vertical.xml

Change the ${ROOT_TAG} to LinearLayout in both of these LayoutResourceFile.xml and LayoutResourceFile_vertical.xml and you will always get LinearLayout as parent for future.
