Out of interest, how LaTeX-ish do you mean? I would hazard a guess that it's impossible to parse an unrestricted TeX file using an LR grammar (or at least no more clear than a hand-coded automaton) because you have to execute the macro expander in order to parse the file *completely* correctly. However, if you only mean LaTeX-ish in syntax (i.e. the files aren't actually TeX files) then you don't have to worry about TeX's elegant (by which I mean terrifying) \catcode mechanism and macro language!
