1. It is unclear to me if the title of "Prince Amedeo"/"Princess Maria Laura" given in their birth certificates and birth announcements was inherited from their father or not. On all Belgian official documents I have seen from prior to 1995 (examples given on request), Lorenz was given only the title of Archduke, not Prince.
2. I don't believe their title of Archduke/Archduchess is non-Belgian. According to the Ministry of Foreign Affairs, it is illegal for Belgian citizens to use a foreign title of nobility unless the title has been legally recognized or incorporated in Belgium (see FAQ 11).

The link you provided says the following:
Prince Lorenz, I assume, did not "officially belong to the nobility of his country" as Austria doesn't have a legally recognized nobility. Nor do I believe that his official ID documents, issued by the competent authorities of his country of original citizenship, mention his "Archduke" title.Une personne de nationalité étrangère qui appartient officiellement à la noblesse de son pays, peut tranquillement porter son titre nobiliaire en Belgique à condition que son titre figure dans les documents officiels établissant son identité, délivrés par les autorités compétentes de son pays.
At some point, I don't know exactly when, I assume Lorenz acquired Belgian citizenship. Even if he had a foreign title recognized at that time in some other country, he could no longer use it in Belgium upon naturalization according to the text above. Moreover, his Belgian-born children could initiate a procedure to recognize their father's title in Belgium, but the father himself could not. As explained in (9), one has to be Belgian by birth to seek such recognition.Quand il devient Belge par naturalisation, il perd son statut nobiliaire de son pays d’origine et il n’a donc plus le droit de porter son titre étranger. La génération qui est né belge peut entamer une procédure en reconnaissance (voir sous 9).
Finally, on Amedeo possibly inheriting the dignity of a prince from her mother when he was born, I can't see any legal basis for that. The Royal Decree of 1891 was very clear in terms of mentioning the "princes and princesses" issued in direct male line descent from King Léopold I. Amedeo is not a direct descendant in male line of Léopold I and it would be odd to assume that he could be a prince in Belgium when he wasn't even in the line of succession to the Belgian throne (i.e. was not a Belgian dynast) at that time.
Anna Astrid's situation, on the other hand, might be different. It is clear from the Royal Decree of 2015 that she is not a "Princess of Belgium" and an HRH, but she is in the line of succession (after his father was reinstated) and she may be a "princess" in the sense of the Royal Decree of 2015 when it mentions:
"Les Princes et Princesses, issus de la descendance directe de Sa Majesté Léopold, Georges, Chrétien, Frédéric de Saxe-Cobourg qui ne sont pas visés par les articles 1er à 3"
deleting previous references to "male line". I also believe that, when the Royal Decree says that the "princes and princesses" in the previous paragraph
"portent à la suite de leur prénom et, pour autant qu'ils le portent, de leur nom de famille, les titres qui leur reviennent de droit par leur ascendance",
it lays down a legal basis for Anna Astrid to be called "Arhduchess of Austria-Este" in Belgium.
What I don't think any of the royal decrees do (either in 1891, 1991, or 2015) is to provide a legal basis for Lorenz's family to use the style " HI&RH " in Belgium. My interpretation why that style appears on the birth certificates of Amedeo or Anna Astrid is, quite frankly, that Princess Astrid and Prince Lorenz pushed it , and the registrar, or whoever was in charge at the time, didn't want to say 'no' to the King's daughter/sister and son-in-law/brother-in-law. I may be wrong of course in my conjecture, but, to me, it reflects very badly on Astrid and Lorenz.
PS: Of course, both Amedeo and Lorenz are "Princes of Belgium" and HRHs (albeit not "HI&RHs") under the Royal Decrees of 1995 and 2015, which are still in force .
