In brief: Death
Legionnaire's disease is a severe bacterial pneumonia.
There are effective antibiotics but the death rate for persons over age 50 hospitalized with this form of pneumonia is reported to lie between 5-30%. Kidney injury has been reported after legionnaire's disease but I have not seen any patients who developed asthma after having this disease.

In brief: Usually death...
The major long term consequence of legionella pneumonae is death or post infectious complications such as kidney failure, pulmonary fibrosis from severe pneumonia, etc.
There a mouse study that demonstrated emphysematous changes and bronchiectasis in untreated mice, but there are no case reports of asthma as a sequelae (consequence).
