As far as he knows no one died. 'Monsters planning to do monstrous things' is situation normal for him.
That's fair, but this is a little bit different in that for all his issues this was supposed to be targeted violence against what's effectively his nationality and ethnicity for lack of a better term.
It's kind of like the difference between gang violence and hearing that someone was trying to set up concentration camps targeted at getting you. Or at least any of your people too weak to defend themselves or flee.
Even if the killing is nothing new the motive is still unsettling to say the least.
Whatever Denarians are metaphysically may not be on Sol's shit list either.
If whatever they're made of post-dates him, then they may simply not have had chance to be entered.
Angels are unlikely to be, and just because these particular angels are having a political disagreement with their creator may not have changed their essence to be something the UCS had expressed his disapproved of.
To be fair, Sol's shit list isn't the only force here in the current age.

In general, mortals "touched" by the supernatu- ral such as ghouls and Kinfolk aren't creatures of darkness. If in doubt, assume that anything that is undead, intrinsically connected to darkness or nightmares, or has been corrupted by or born from forces of cosmic corruption or entropy is a creature of darkness, while anything else isn't. This does, it should be noted, mean that some creatures of dark- ness aren't really "evil" in the conventional sense (Sluagh fairies, for example, are born of nightmares but may want to do nothing more offensive than drink tea in their favorite musty old bookshop and frighten children who are too loud), but intrinsical- ly evil beings are always creatures of darkness (such as Banes). Abyssal, Liminal, and Infernal Exalted are always creatures of darkness
So the criteria seem to have been updated with the changing of the world to something more fuzzy than one god's opinion.
WoD Demons are CoDs, despite also being Angels and falling without the Big Yellow One's notice.
I'd rather assume that Lash doesn't count as CoD because she's build from Harry's mind, than believe that Lasciel is not a CoD.
Per the description you just have to have a strong connection to one of a few things or be inherently evil.
Which, if I'm tracking her character arc correctly, she still is. She's getting better, but there are still some significant things they need to go through together to push her redemption plot measurably forward.
For my part it makes more sense that she isn't showing up because she's hidden inside Harry, sort of like nemesis.
I bet if he started channeling hellfire or something she might show up a bit, but right now the power she's exerting is entirely contained within Harry body and is low energy anyway.
A more interesting question is if EDS would see her:
essenCe-disseCting stare (•••)
The Infernal's stare rips away the pretenses of pro-
saic reality, allowing her to see through to the truth of the cosmos.
System: Roll Perception + Occult against difficulty 7. Success allows the character to see the aura of power emanating from Dragon Nests. These appear as rising
auras of Essence, visible from up to (Essence rating) miles away. Spending 1 Willpower permits the Infernal to attune her senses to the vibrations of another realm of existence for a scene, seeing through the Gauntlet or Shroud and into the Penumbra or Shadowlands, or to behold reality's chimerical aspect.
In the literal mechanical sense it doesn't, but we do have other charms/abilities that more more off fluff than system text alone.
Seeing as mortal minds partially interact with the nevernever while doing things like dreaming, which we know from the dream magic path, wizards definitely passively interact with the magical energy around them, and Lash has multiple* outgoing connections, it's possible that we don't see her as a CoD because she's shielded from the perspective we're looking at but would show up as a disturbance in Harry's normal interactions with the environment relative to his prior/the standard wizard baseline.
Not as something screaming what she is or how she's feeling like HC can see, but something noticeable at least.
* but likely subtle
