I would set up a included squid.conf snippet with 24
tcp_outgoing_address settings (one per hour, selected by acl) and update
this file nightly to assign a new set of IP addresses for the next day.

generate_random_outgoing.sh

#!/bin/sh
top=`dirname $0`
HOUR=0
cat $1 | sort -R | while [ $HOUR -lt 24 ] && read ip; do
  printf "acl hour_%d time %02d:00-%02d:59\n" $HOUR $HOUR $HOUR
  printf "tcp_outgoing_address %s hour_%d\n" $ip $HOUR
  HOUR=`expr $HOUR + 1`
done

Usage:
generate_random_outgoing.sh /path/to/file_with_ipaddresses.txt >/path/to/etc/squid/random_outgoing.conf
squid -k reconfigure

and in squid.conf

include /path/to/etc/squid/random_outgoing.conf
