Is your feature request related to a problem? Please describe.
Google Copyright should be written similar to Copyright 2010 Google LLC. Currently, a lot of our existing code has copyright enforced as Copyright {Year} Google Inc..

When we make a code change, we should enforce that the header should be updated to Copyright {Original Year} Google LLC

Describe the solution you'd like
When there is a modification to the Java code, we should have a check to ensure that the header is modified to the correct value.

Describe alternatives you've considered
Could the checkstyle plugin be enhanced so that it is enforced on updates? Or can we write a script to check for modified files and check that the copyright is being updated to LLC?

The current checkstyle plugin only checks that it follows the regex in java.header. Since we have whitelisted either Google Inc. and Google LLC, it is currently not being enforced.
