Yes I know you don't understand the through line, because you are still mischaracterizing what I'm saying. If districts want this funding, they HAVE to provide some form of afterschool care. However, the funding is not enough to allow them to hire, train, and give the necessary resources to entirely new staff for this purpose. So they will have to rely on existing staff, staff who (per the language of the bill) will not be paid overtime. The bill says they can't make the extra hours a requirement of teacher's employment (as in, they can't write it into their contracts as mandatory hours) but that does not preclude them from pressuring teachers into volunteering to do the afterschool care. This kind of thing happens in schools due to a lack of funding all the time, teachers often end up pressured into doing things not in their contracts (for example, buying supplies for their classrooms out of pocket).
If the bill actually provided the resources to build these programs in each school from the ground up, this would be less of an issue. But that's not the legislation being proposed.
