We have around 20 API GW, at least 20 dynamodb tables and more than 30 lambdas, several queues and opensearch replicated across 2 environments (dev and prod) plus additional programming environments (cloud9) and we barely come close to half of what you you are budgeting here for. Your math is wrong.

How big are those Opensearch clusters ? Lets take a small production cluster of 4x r6g.large (default proposal for prod) (0.167$/h) deployed in VPC in private subnet (x2 for HA) That’s 16$ per day for instances only and 2.5$ per day for nat-gateways per day. So 18.5$ per day and ~550$ per month. Thats ofcourse if you disable all metrics all logs all alerting etc and it does not include Volumes cost, because its highly dependent on the domain. AWS is expensive because you get alot of administrative work out of the box (snapshots, restores, etc). Tho sometimes have to still fix in the source. Ive personally pushed quite a few fixes to OpenSearch source, coz version 1.0.0 had a lot of issues.
