Elmira, thank you for your contribution. Your change removing toll:hov and adding toll:hov:conditional implies that vehicles meeting the current HOV minimum still have to pay tolls outside of the HOV-exclusive times of (Mo-Fr 06:30-08:00,16:30-18:00). I don't think this is the case. HOV vehicles (3+ during Mo-Fr 06:30-08:00 and 2+ all other times, including weekends) never have to pay tolls in the express lane, according to "How much does it cost to use the express lanes?" in https://www.ridemetro.org/riding-metro/hov-hot-express-lanes. My previous tag toll:hov=no fully described this behavior.
