You may not like it, but propane and natural gas leaks result in explosions, then fire. One near me leveled the house and killed both occupants, after they malingered in a burn unit for a month. Most battery fires are fires, they don’t involve explosions, so while both are horrible, your chance of escaping a battery fire with your life are vastly better.
It would be useful to compare facts: Here is 2018 data for natural gas (not including propane):
Local fire departments responded to an estimated average of 4,200 U.S. home structure fires per year
that started with the ignition of natural gas. These fires caused an average of 40 civilian deaths, 140
civilian injuries, and $54 million in direct property damage per year

Health Canada says cellphones and smartphones now take the top spot of electronic devices that are causing fires.
There were 183 fires reported across the country over the past five years involving phones and their accessories.
The second most frequent cause of device fires was thermostats, with 104 reported fires between January 2016 and last September.
Computers, laptops and tablets landed in the third spot with 74 fires reported, while only 34 fires were attributed to TVs.

Whatever the extent of destruction of lithium batteries, comparing it to natural gas explosions is meaningless. Electrical fires, in general, cause far more property damage and deaths than natural gas fires:
According to the U.S. Fire Administration (USFA), there are 28,600 electrical fires per year. These fires cause $1.1 billion in property damage and loss and are responsible for 310 deaths and 1,100 injuries each year. The months with the most electrical fires are December and January due to increased use of heating appliances and lights.
