Howdy, Anyone know how to change the user who installed a bundle or the user the scripts are executed as from bundles?

I don't think you can change bundle owners unless you maybe uninstall and reinstall a bundle ( would not suggest this it could break things) Scripts are executed as a role that you can find in the script deployment.

Bundles should really be installed using a service user if possible to avoid issues with being tied to individual users, but oddly it's not something NS (or most consultants I ever worked with) ever suggest.
