Not quite. Please note that there are various things you pay for, let's take a look at several of those:

- provisioned resources (instances, including the ones under relational databases or other stuff like that)

- usage of on-demand resources like AWS Lambda and API Gateway

- infrastructure such as load balancers (kind of mix of provisioned and pay-per-use)

- persistent storage (which is all over the place in terms of payment methods)

While you could shut down the first three to save some money, would you like to remove your data permanently?

So far all mechanisms that are available are mostly reactive (billing alarms etc) rather than proactive (service quotas although they are meant to shield from poor design rather than a typo in terraform). There is clearly incentive for cloud providers for the former, but it's not an easy problem anyway (they might mark your accounts for "training" or something like that - I think this would be reasonable).
