Tell your friend to check her emails, especially spam.   If LL deletes an account they email and tell you next steps

She says "They informed me that my account was deleted but they didn't explain the reason".

could be she did it herself... or if it was LL, it will be a ban, not deletion.
In the last case you or she, or we... can do nothing.
A ban is always confirmed by email with a general indication of reason, never specific.
In most cases the one that gets banned knows pretty well what the reason is.
