Check how rollback is going after killing session
                                               
Summary
If you kill a session and has uncommited transactions you must wait until rollback. To find how rollback is going execute

SELECT used_ublk FROM v$transaction WHERE ADDR IN (SELECT TADDR FROM v$session WHERE SID = <SID>)

where sid, is the sid of the killed session

If there is a value there, this is the number of undo blocks used by the transaction. Wait one minute and again. If it is decreasing, a rollback is occuring and based on the difference between these values, you can "guesstimate" the time required to complete the rollback.
Output will be like the below
SQL> SELECT used_ublk FROM v$transaction WHERE ADDR IN (SELECT TADDR FROM v$session WHERE SID = 304);
