Are there any legal government jobs that start out at GS-11 that aren't that hard to land?
Not really. Base salary for entry-level attorneys is at GS-9. GS-11 is usually for Honors Program entrants. The agencies that pay more than GS-11 starting (SEC, USPS, etc) are even more competitive.
The scary thing is that applications from attorneys are now flooding the market for quasi-legal job titles. I've spoken with attorneys from DHHS, DOD and EEOC who have told me that they're getting hundreds of attorneys applying for job titles like paralegal, examiner or investigator, that are GS-5 or GS-7.
