This is the kind of thing why school choice vouchers can't exist in any good faith context. Private entities wouldn't be held to the requirements that they answer these kind of nonsense requests, or even if they did, wouldn't be beholden to the public to consider changes to material that someone objected to.
Any request with a perceived political motivation should be paid in full before any work is started, others may have some leeway in their arrangements but still need to be compensated by the party requesting excessively broad datasets. If you want input into the curriculum, attend a PTA meeting and speak your piece publicly.
