First time: "Apple TOS violation"

After having good experiences with way older iMacs (as old as 12,1) I wanted to use OCLP to bring my iMac 18,2 to Sequoia.
When starting OCLP I am getting this and it indeed removes OCLP from /Applications/.
This happens when I am starting OCLP on the target machine when I wanted to create an installation medium (USB).
Is there another way, except for creating the installation medium on another Mac?

Thanks, doc.
