Don’t you need an SRE or Devops focused person regardless?
You still need a way to test and deploy the code your pushing. You also need to set up logging and networking that ties it into the rest of your systems

We don't have an operations team, so each dev deploys their own services; this framework gives them all a consistent interface so we know how to test or deploy someone else's code.
Advantages from my POV:
* zero or simplified ops; no load balancer setup etc.
* we don't pay for idle hardware
* scales well by default (built with parallelism in mind)

You mention that serverless.com offers a sort of PaaS that simplifies your life. That's similar to Heroku, which does the same thing but with regular servers and similarly allows you to defer having a dedicated Ops person. Having worked at plenty of places that leveraged PaaS's for most of their needs, I'd say it's normal to not have an Ops team until you begin hitting issues around general maintenance and secure networking setups.
I was the fourth engineer at a smallish currebtly Series A startup that used lambdas for ~90% of their services and we ( the software devs) built the CICD, API gateway integrations, all of that stuff. We figured out a good solution early and then maintained it. Which made moving forward pretty trivial.
It only got a little bit more complicated as we wanted to use different authorization methods or VPC private link when we did eventually spin up a couple ECS clusters.
The company now has a full-time DevOps/SRE, but they don't really work on the code deploy CI stuff. They more deal with I am audits and security and stuff...
I'd argue that the need for someone focused on SRE/Devops comes from factors that are mostly unrelated to whether or not you go serverless.
