Yes. API way can add 100,000 records in 3.5 seconds.

Records have 13 fields in this test.

No, SqlLite is special here :-)
All  normal dbs become slower on transactions.
    
    SqlLite is faster with transaction because EACH transaction
    open/close disk file. IT do not have cache at all.

    So if you self start transaction then you avoid thousands
    of open/close in SqlLite.
    
IF you want use SQL and not Api, then the best way to use parameters:

    query = "INSERT INTO T1(f1,f2,f3) VALUES (?,?,?)"

Look into SQL_Way/Bind example
