For which you have to file them first, for which you need to know the specific rules applying, for which people are using an expert, or AI.

No, the other party should file them. Charities can file the lists of donors etc.

What other party? They often don't even know you or if you can use something for tax or not. Pretty much everything can be used for tax deduction, it all just depends on circumstances. I know, many countries have a really broken privacy-situation, but I don't think it would be realistic that every shop is preventive filing every receipt and forces every customer to give them their tax-number so they can link them..
