Looking through LWP::Simple, LWP and lwpcook, I couldn't find documentation on accessor methods but found that some methods were available (through experimentation :-) ). I've documented some of them in the code below. 
#!/usr/bin/perl
use strict;
use warnings;
use LWP::Simple;

my $req = head("http://perlmonks.com"); # request

if ($req) {
    print "protocol:\n\t",
        $req->protocol, "\n";
    
    print "headers->etag:\n\t",
        $req->headers->{etag}, "\n";
    
    # a leading underscore is considered 'private'
    # and probably should not be accessed
    print "_rc:\n\t",
        $req->{_rc}, "\n"; 
    
    print "request->uri:\n\t",
        $req->request->uri, "\n";
    
    print "request->headers->{'user-agent'}:\n\t", 
        $req->request->headers->{'user-agent'}, "\n";
}

Output was: 
protocol:
        HTTP/1.1
headers->etag:
        "e047-525cb6d2fef00"
_rc:
        200
request->uri:
        http://perlmonks.com
request->headers->{'user-agent'}:
        LWP::Simple/6.00 libwww-perl/6.02
