There are 2 types of opper (as you call them) on IRC.
One is a opper - this person has the power, to kick and ban people off servers.
And a OP - This is what you are on about.
Eggdrop is designed for channel control. That is what it's internal goal is.
The best thing you can do, is to remove the message being sent to the channel, regarding wanting OP's, and to disable/dumb down the settings for a channel (see ".help chaninfo" an ".help chanset" in the partyline).
#This is the procedure which is run during connect
proc identconnect {init-server} {
global pass
putserv "Privmsg Nickserv :Identify $pass"
putserv "Privmsg Chanserv :Op ALL"
putcmdlog "Nickserv On Connect Identify Attempted"
}
