My bird (budgie) also doesn't care for toys! Sometimes I worry about it and sometimes I don't. His mate loved toys that she could rip apart. Her favorite was a yucca chip toy which she would reduce to shreds within a week! She liked other shreddable toys too. She would climb, stretch her neck, get herself in precarious positions, learned how to swing something so it would come back to her and she could catch it... just to play.
However my male will only touch a toy if it happens to be right next to where he's sitting. Even then he'll just nibble at it for a few seconds, or tap his beak against it while he sings. There's no way he'll put effort in just to play with a toy (though he will do it for food so I sometimes hang treats in precarious spots to make him work/think for it).
Sometimes I feel worried it means he's not getting enough enrichment, but honestly I think it's mostly just a matter of personality. I know he knows how to use toys because he watched her and sometimes played with her--but never for as long or as enthusiastically as she did. BUT on the flip side, he loves to fly. He will fly around the room just for fun and has impressed every vet he's seen with his flying skills (he has quite good endurance, agility and precision for a pet). My female, on the other hand, only used flying as a means of transportation, had trouble landing in the right place, and preferred to just climb unless she was following him. Also she would chirp sometimes, but not like him. He loves to sing and chatter! He also enjoys looking out the window and just observing everything around him, which she never much bothered with.
So, I still give him some toys, but not as many as I did when she was alive. I offer them but don't really try to push it. As alternate mental and physical enrichment, I try to cater to HIS preferred activities. I give him varied sounds to sing to, and talk to him a lot (he doesn't say actual English words but his vocal repertoire continues to increase, regularly adding new sounds). He has a play stand by the window so he can watch people/cars/trees/squirrels/birds (if I don't open the blinds early enough for his liking then he will remind me). He has more perches than toys (on the outside of his cage so he has different landing and singing sites---different shapes, materials, etc..) And I let him stay out of his cage all day so he can fly whenever he feels like it! (Don't worry...I do put him in his cage for bedtime)
Since he doesn't care for toys I also keep an extra close eye on his beak to make sure it doesn't get overgrown...but although he ignores actual toys he does enjoy chewing on perches occasionally, so it hasn't been an issue.
I think parrots have such varied personalities... and maybe just like some humans have hobbies that others don't care for, the birds don't all enjoy the same things to the same extent either.
If your bird doesn't seem interested in anything at all you might see a vet. If he's active but not too interested (which sounds like the situation since he's willing to forage) you can just try as many types of things as you can until you find something he enjoys more.
