I don't have in depth knowledge of Cisco's SNMP implementations, or even the ASR platform specifically, but if Cisco TAC is telling you this is 'normal', they are completely full of shit, and you should click any and every 'escalate' button you can find.
This almost sounds like a default control plane DDOS policer / LPTS , something like that.
There are various complicated reasons for this, LPTS policer is unlikely culprit, but possible. Bug search will show various DDTS with poor SNMP performance outcome, most of them are unrelated to LPTS. But absolutely correct, the right solution is to escalate. In common case this would be SE from your account team, who would fight for you internally. It is appalling that OP came to nanog after correctly suspecting TAC is gaslighting them, some community member piled on with what can only be described as a bizarre drivel. -- ++ytti
