You have developers that don't know how to fix this? I'd suggest
hiring someone that knows JavaScript.

By your description I assume you've added something like this:

  onclick="alert('uncheck me')"

If thatt's the case, you can switch it to do what you want by changing it to:

  onclick="if (this.checked) alert('uncheck me')"

However, your accessibility problem comes not from the alerts but from
the fact that you're using checkboxes for validation. I can't say for
sure since I haven't seen it, but you may want to reconsider the user
experience aspect of your web app.
