Yes, you can. Since OpenAPI itself has a JSON schema, you can get autocomplete from any editor that supports JSON schema.
At my company, we found that the auto-OAS generation tools were too brittle and didn't communicate enough information, so we actually do write our own OAS and run automation to make sure it's accurate.
That's also how our architects communicate with developers about an endpoint - create an OAS for it.
