I have set docValues=false on all of the string fields in our index that have indexed=false and stored=true. This gave a small improvement in the index size from 13.3GB to 12.82GB.
I have also tried running an optimize, which then reduced the index to 12.6GB. Next step is to dump the sizes of the Solr index files for the index version that is the correct size and the version that has the large size.

I will try setting docValues to false, as we only ever want to be able to retrieve the value of this field.
