I haven't used delay pools in a while, but I would think that the updated Squid 3 delay pools (with 64-bit counters and per-authenticated-user buckets) would allow such quotas.
I'd take the monthly quota and turn it into a per-second rate. If my math isn't failing me, 100 GB/month = 38,500 bytes per second. That would be the refill rate on the delay pool. Users will be guaranteed this rate. Their BW would never be cut off, just throttled to the rate they're paying for.
Then pick a max value to taste. I like to populate delay pools to support an enormous burst size (the "maximum" parameter in the pool), so the bandwidth limitations will rarely if ever be encountered by the average user. 10% of the monthly allotment, or 10 GB, (3 days' worth of bandwidth) strikes me as a good starting point, but I wouldn't have much resistance to even higher numbers, like 25%.
