Export Solution:Ok, I will write a more detailed method later.
Basic Method:After drawing something you may have more than one layer in LiveBrush.
Make sure you select, highlight, every layer you wanted to export BEFORE next step.
Under the File Menu select Export then choose, Export Line(s) to SVG
Name the “__.svg” file and save it wherever you can find it easily
Adobe Illustrator can read SVG files and the images WILL be vector graphics that you can edit within Ai.
To use in Photoshop, save the Ai file as an Ai file “__.ai” and PS will bring it in as a high-resolution image (you choose i.e. 300 dpi, RGB etc. during import to PS from Ai).
Alternatively, you can COPY the Ai vector graphic(s) and PASTE into Photoshop choosing (Smart Object, Pixels, Path, Shape Layer.) Some of these methods allow you to use the Direct Selection tool and the Bezier Curve/Points editing tools afterwards.
Enjoy, experiment and share success!
