Probably, it all depends on what result you want to get. As @Anssi said, AutoCAD does not perceive LO patterns as vector graphics, but that does not mean that it is not possible to transfer an object with a LO patch to the AutoCAD environment without losing its appearance. Only then will it be a raster patern. When exporting, a group of objects will be created from each object, where each of its subelements will be limited both by the size of the pattern module and the boundaries of the object. It is best noticed by objects made of curved lines.
Another peculiarity will be that this object is not exported to the CAD model environment but to the layot environment (in this case it will be Page1) only. You can get it into the model space with Ctrl+C - Ctrl+V.
