It's not "lh" it's a double ell. It's written in Gothic cursive and there's really no doubt about it being double ell if you are familiar with Gothic cursive script. Look at the last page and you can see that whoever penned this and the text on the last page does not write "h" that way. No one did at the time this style of script was in vogue (which was primarily the 15th century). It either had a hook leg or a rounded leg, not an angle leg as seen here. Also, it was very common to not dot the "i" (or to dot only some of them). It is an "i" with a beginning serif, just as they are written on the last page. Note the slight gap between the serif and the ell.
Also, the fleur de lis shape looks like a flower head in the same drawing style as the other flower heads in the manuscript.
