I agree that it seems somewhat "off" that trolls/dwarves don't pay extra for lifestyle due to their extreme ergonomic needs if they pay extra for gear for that same reason.
However, I'm not inclined to agree that it looks like they "should", given the language used in this edition.
*putting rules lawyer hat on*
The basis for saying they should pay that extra bit for lifestyle is twofold: 1) it worked that way in 5e, and 2) its says they pay extra for "everything", and lifestyle counts as something encompassed by "everything".
To rebut: 1) doesn't count for anything if it's specifically contradicted in this edition, which it appears to be. It says they pay extra for gear, not for lifestyle. "But lifestyle counts as 'everything'" segues into 2) By that rationale, then they must also pay extra for karma costs, since buying skills/attributes counts as "everything", does it not? And there's zero indication of that being the case, by RAW or by RAI, elsewhere.
Ok, so "obviously" when it said everything, it meant just "everything paid for in nuyen"? Well, now we're diverging from RAW and coloring the reading with opinion, and that undermines the whole argument "by RAW it says 'everything!'" to begin with. But further than that, other things can be paid for in nuyen, too. Namely, bribes and fines. Again, there's no support anywhere else that Trolls must pay more when bribing or fined, just because they're trolls.
The flipside to all this hand-wringing about whether things beyond gear are covered by "everything" is to simply presume that they are not. It's a rule presented in the gear section. Contextually, it's easy enough to presume that the rule only applies to gear. I think that's the stronger way to read it, and therefore "everything" does not apply to lifestyle because it is not gear.
Of course: YMMV.
