Please HELP!! US-LLC owner German citizenship and tax&life residence in Paraguay

Hello, I hope you would be able to help solve this case:

- German citizen with tax and migratory residence in Paraguay.

- Own a sole member US-LLC and need to bill international customers in USD and EUR.

- I have SSN/ITIN number as I lived and worked for a year in USA

- WISE rejected me 4 months ago as they don't operate with Paraguayan residences (at that time at least).

- Tried AIRWALLEX and rejected me with no explanation given, and I had lots of hopes here as they have low fees and give me an IBAN (EUR) and USD bank account as well

Please could you help me solve this or advise a fintech that works in my specific scenario??
