Just did a check of some websites & your right nobody seems to carry MO LME.
I would use Pilsner
DME or BELGIAN_PALE_EXTRACT
<forgot to ask, are you doing some version of this recipe?>
Ingredients: Pilsner malt
(French barley from Champagne) & caramalt; German Hallertaur & American Galena hops. Yeast & sugar added to the bottled beer.
Chimay Rouge (Red) is noted for its coppery colour which makes it particularly attractive. Topped with a creamy head, it gives off a light, fruity apricot aroma produced by the fermentation. The taste perceived in the mouth is a balance confirming the fruity nuances noticed in the fragrance. Its taste, which imparts a silky sensation to the tongue, is made refreshing by a light touch of bitterness. To the palate, the taster perceives a pleasant astringency which complements the flavour qualities of this beer very harmoniously. This top fermented Trappist beer, refermented in the bottle, is not pasteurised
