When I visit the site in a browser and I click on a random item, it tells me to enter a catpcha (but I can't solve it because I can't speak russion nor do I know these symbols). Shouldn't the ouput from youtube-dl be that you have to enter a captcha?

The site also says:
"we recommend using the specially designed for this purpose service Yandex.XML"
Is this possible?

youtube-dl can't solve captcha. Once you solve it you can pass cookies to youtube-dl with --cookies. Note that it may only work in Russia, Ukraine, Kazakhstan, Belarus and Turkey.

Of course it can't do that, but I mean that it should show an error message that a captcha has to be entered in the browser instead of "No JSON object could be decoded", if that's possible.
