I've been able to write scripts that run when auto-connecting to such 
networks.  For instance, to auto-promise that I won't do anything 
illegal on the library network, in 
/etc/NetworkManager/dispatcher.d/30-ffxlib.sh I put:

#!/bin/bash

event="$2"
conn_uuid="$CONNECTION_UUID"
ffxlib_uuid="36e9d273-4c64-49d8-a49a-918a84a25163"

#echo '----------------'     >>/tmp/nmlog
#date     >>/tmp/nmlog
#id    >>/tmp/nmlog
#echo $* >>/tmp/nmlog
#env    >>/tmp/nmlog
#exit

if [[ "$conn_uuid" == "$ffxlib_uuid" ]]; then
  case "$event" in
  up)    cd /tmp
    wget -Y 0 https://ffxwlc.fairfaxcounty.gov/login.html
    wget -Y 0 --post-data \
'buttonClicked=4&err_flag=0&err_msg=&info_flg=0&info_msg=&Submit=Accept&redirect_url=start%2efedoraproject%2eorg' 
\

It would be difficult if not impossible to auto-create such scripts for 
arbitrary click throughs.  However, I've noticed that most click 
throughs (where no password is required, but you promise not to break 
the law) are from a small number of router engines, with added window 
dressing corporate logo, and advertising.  It might be possible to 
recognize these and auto-promise (of course, NM should first ask the 
user to pinkie promise not to break the law on *any* network so 
auto-connected).
