Hey @TamD 
I was able to enable Liquid Clustering via DLT using the below Syntax.
Try it and let me know if you face any issues:

import dlt

@dlt.table(
    comment="DLT TABLE WITH LC ENABLED",
    cluster_by = ["column1","more_columns"]
)
def name_of_the_table():
    df=logic_to_create_the_table
    return df
