I found finally found a workaround that works for me
I used this tool
https://rcebits.com/lsd2dsl/ to convert Lingvo’s LSD files to LSD files.
Next I used
https://github.com/ilius/pyglossary to convert the LSD files to Stardict dictionaries.
Now I can use the dictionaries with the ColorDict app which is even better because popup of the Lingvo app only showed results from one dictionary at a time and only showed an excerpt of the dictionary's entry. ColorDict shows multiple dictionaries and the full entries in their popup.
