It sounds like you have wooden toys, maybe try different materials? My cockatiels are kind of picky when it comes to toys as well.
Mine like to shred paper toys, so I'd try something like this:

If your bird isn't playing with its toys, you can try to hide some food inside of it, that worked for mine.
Something I haven't seen that much but mine LOVE are cork platforms, they shred and play with it for hours. Heres an example:

If you have the option to do so, I also recommend giving them freshly cut branches of non-toxic trees. Its the best when the leaves are still on. The birds love to nibble at it and destroy the leaves, it's also natural for them!
You can also just use paper strips to make your own bird toys, there are plenty of youtube tutorials, like this one:
Or - something I haven't tried - you can use a box and fill it up with different natural materials or parts of broken toys and then hide some food at the bottom, this way the bird will have to play with it to get the food, something like this:
Thats all I can think of right now - good luck
