I've always just used qrencode, which is a standalone program available for Linux and Windows. I also use ZBar to verify the generated QR codes. It never occurred to me to use a web app for this.

It is/was actually unsafe and privacy-harming to use Google charts (and any other API for that matter) for generating QR codes on anything related to cryptocurrency.

You can generate QR codes browser-side with a Javascript library like https://davidshimjs.github.io/qrcodejs/

It's extremely easy to use. Make sure you self-host the .js file to avoid any potential attacks.

You could potentially use a site such as imgur.com to achieve this if you don't host your own website.
Alternatively, you could upload your images to Google drive (or Facebook) and get the image url from there which can then be shared.

As Google Image Charts is being turned off, what's a reliable way to generate these images? Obviously I don't want to use any site that can't be trusted.
