The example below is based on file names and examples in 
goodies/logformat.cfg.

You could do this:
1) Copy Radiator's LogFormat.pm to /etc/radiator/CustomLogFormat.pm
2) Find and update two instances of
    "Radius::LogFormat" to "CustomLogFormat"
3) Locate accounting log JSON formatter by looking for
    "sub format_acctlog_json"
4) Look for "acct_status_type" and add "framed_ipv6_address" in the 
similar fashion. You need two changes in the sub.

You can use radpwtst for testing:
perl radpwtst -trace 4 -noauth -nostop 
Framed-IPv6-Address=2001:db8:148:100::31

This sends a single accounting start request. Your JSON log should have 
a new JSON key-value pair like below:

{...,"framed_ipv6_address":"2001:db8:148:100::31",...}

When it works, trim your CustomLogFormat to match your requirements.

Thanks,
Heikki
