I've played a lot of BG1 & BG2 over the years, and having a thief in my party was critical (at least in my opinion) for traps & locks (of which there were a lot of), but in BG3 there's only one companion with thief skills. If I don't take him along, and I don't create a thief-type character myself, do you think that will be a problem? I know there's the "knock" spell for locks and the "find traps" spell, but those take up precious spell slots. Also, we only have 4 party members total instead of 6 like in BG1 & 2, so it's going to be harder to chose who to take along.
