yes, they are being phased out but a lot of them are still being kept to aid in navigation in the event of gps outages.
from an
article in the May 2018 AOPA magazine:
As of April, the FAA had discontinued 23 of the more than 300 ground-based navaids it plans to shut down by 2025 as more aircraft equip to fly performance-based navigation routings enabled by GPS. Selecting navaids for removal involves evaluating whether a navaid should be kept in service as part of the minimum operational network, which will serve as a backup system designed to ensure that an aircraft can navigate to an airport within 100 nautical miles of the navaid and shoot a VOR or ILS approach there in the event of a GPS service interruption.
