Literally just buying an insurance policy is significantly less complicated and roughly the same cost, IME. Professional liability, errors and omissions, etc. cost me ~$1k a year when I was doing consulting for $1mm in coverage. My LLC taxed as an S-corp cost more than that just in tax prep services.
A single member LLC provides some benefits but those benefits often require a lawyer to invoke (i.e. you're getting sued, gotta file things and work the legal system). If you have insurance you just tell the insurance company and they hire the lawyers.
