Not sure sonic is a replacement for Elasticsearch in terms of ELK as "Sonic is an identifier index, rather than a document index; when queried, it returns IDs that can then be used to refer to the matched documents in an external database", i.e. you will have to either find a way to resolve your ids back to the original documents (which may be difficult in case you have logs rotation, retention etc.) or in addition to Sonic store the docs somewhere else.

There's also Loki - https://github.com/grafana/loki which integrates with Grafana natively which may be the Kibana replacement you're looking for.
