Hi @Derek Galon5,
thank you for reaching out.
You can export to standard CUBE files either as 15x15x15, 33x33x33 or 64x64x64.
In Premiere you can import them via the Lumetri panel or with any LUT handler of your choice like you would with every other LUT.
A plugin for Premiere Pro (like it is already with the OpenFX Plugin for DaVinci Resolve) is definintely on the Roadmap, but currently there is only the way mentioned above to bring your grade to Premiere.
