There _are_ options to suppress these messages:

"zoo e//O"   unpacks an archive with complete directory tree and without
             asking questions and without overwriting files
"lharc -m e" does it too. (for .lzh-files)

Writing a device would be a bit of work. What about using pipes?
I'm using ARP and the conman-handler to get real (unnamed) pipes.

The yes-program:

main(argc,argv)
int argc; char *argv[];
{
    if(argc==1)
        while(1) printf("y\n");
    else
        while(1) printf("%s\n",argv[1]);
}

Your command would then look like

yes n | zoo e//
