SearXNG is an AGPL licensed meta search engine that has multiple instances running by the community along with plenty of integrations and the ability to self host. Presearch does not have AGPL licensed server code from what I can find.
In terms of privacy, Mullvad Leta + SearXNG is just better from what I see. It’s not perfect, as Leta is minimal, and SearXNG instances get blocked easily. But I can self host SearXNG today and can validate code running on other instances. Leta already has reputation because of Mullvad. This these two generally protect against all of the things you say you are protecting against.
If you are suggesting that your service still needs to be accessed via Tor / VPN for anonymity, then I don’t know what the decentralizations strategy does for an end user that SearXNG doesn’t solve by accessing it with Tor / VPN. It’s either trusting Presearch the company, Mullvad whose been in the game and trusted for a while, or a SearXNG instance operator.
I’d like to be sold on why I should bother switching when I have these two options together.

Some additional questions to help with the above. Perhaps these are in your docs, but these seem very relevant for discussion here as part of discovery for readers:
Is Presearch doing its own indexing atop the integrations, or what other advantages are there compared to SearXNG / Leta accessed via Tor? Are your integrations through official channels or scraped like SearXNG?
Does Presearch plan on licensing their server side code as AGPL, or another FOSS license? Or did I miss the repo.
If it’s decentralized, and there are nodes, are the nodes run by the community? Is this also AGPL licensed? What query metadata is propagated through the nodes?
Aside from ads, how does Presearch make money? Do you get paid for doing specific integrations? I ask the latter as there are a suspicious number of crypto integrations built in. Are you a VC backed company? Do you get paid for click through rates with integrations?
EDIT: this isn’t to say I’m against it, but Im highly skeptical of companies providing free-ish services that say they respect privacy without a clear conversion plan. There’s a bottom line somewhere, and it must be reached. If that bottom line is Malware ads - fine, I can live with that. However, uBlock will catch up and block them, and the privacy crowd all has this installed - how will money be made? How will this service be maintained?
