In fairness, a paladin wouldn't know the nature of all their companions that soon. Shadowheart comes off as perfectly reasonable. Lae'zel is violent, but potentially manageable. Astarion's kind of an asshole but one who keeps in line, Wyll is a rambunctious hero, Gale is a pompous academic. All stuff a lawful good paladin would find acceptable if not ideal in an extreme situation such as this.
Also I resent the idea of Lawful good being entirely inflexible and a maker of 'problems'. They aren't automatons incapable applying their own thoughts and interpretations to situations, and making judgement calls to bend the rules but not break them. Also what lawful means can alternate from person to person. For instance with Wyll, yes he made a deal with a devil, but he regrets it and wants out. A lawful good paladin could easily look at him and think 'I should help this man get free of his pact and find true redemption.'
I agree that it’s perfectly possible to rationalise working with the current crop of companions as a lawful good character, but I think there are also lawful good characters who reasonably wouldn’t want anything to do with some or most of them once their secrets have been revealed. And while it’s okay to be forced by the story to work with people you wouldn’t want to normally, I think it would be a pity if the latter sort of lawful good character didn’t have the opportunity to build a core party of more like-minded souls. And given many Paladins are, from the nature of their oaths, going to tend to be less willing or able to compromise than other classes, I feel they’re likely to be over-represented amongst those who find it harder to create a congenial party from the current companions.
There’s a similar problem when going all out with the evil, though it seems more plausible that really nasty characters would find it difficult to work with others so that bothers me less. But I still hope that there will be further evil companions to be found in the full campaign.
