You can block access using an LTM policy. This has rules in which you select URIs etc and is more performant than an iRule.

Regarding your iRule, you seem to have used starts_with but the URI doesn't start with /ologin, it starts with //. Maybe use equals or ends_with instead:

when HTTP_REQUEST { 
  if { [string tolower [HTTP::uri]] equals "//ologin" } { 
    HTTP::respond 404 noserver return 
  } 
}

You can also use HTTP::path which may be a bit more accurate as it doesn't contain the query string.
